MC74F803 FUNCTIONAL DESCRIPTION The F803 consists of four positive edge-triggered flip-flops by-two driver for high-frequency clock signals that require with individual D-type inputs and inverting outputs. The buff- ered clock is common to all flip-flops and the following specifi- symmetrical duty cycles. The difference between the LOW-to- cations allow for outputs switching simultaneously. The four flip-flops store the state of their individual D inputs that meet HIGH and HIGH-to-LOW propagation delays for the O0, O2, the setup and hold time requirements on the LOW-to-HIGH and O3 outputs vary by at most 1.5 nanoseconds. These out- Clock (CP) transition. The maximum frequency of the clock puts are very useful as clock drivers for circuits with less strin- input is 70 megahertz, and the LOW-to-HIGH and HIGH-to- LOW propagation delays of the O1 output vary by, at most, 1 gent requirements. In addition, the output-to-output skew is a nanosecond. Therefore, the device is ideal for use as a divide- maximum of 1.5 nanoseconds. Finally, the IOH specification at 2.5 volts is guaranteed to be at least – 20 milliamps. If their in- puts are identical, multiple outputs can be tied together and the IOH is commensurately increased.

MC74F3893A QUAD FUTUREBUS BACKPLANE TRANSCEIVER (3 STATE + OPEN COLLECTOR) The MC74F3893A is a quad backplane transceiver and is intended to be QUAD FUTUREBUS used in very high speed bus systems. BACKPLANE TRANSCEIVER (3 STATE + OPEN COLLECTOR) The MC74F3893A interfaces to “Backplane Transceiver Logic” (BTL). BTL features a reduced (1 V) voltage swing for lower power consumption and a se- FAST™ SCHOTTKY TTL ries diode on the drivers to reduce capacitive loading (< 5 pF). 19 8 FN SUFFIX Incident wave switching is employed, therefore BTL propagation delays are 34 PLASTIC short. Although the voltage swing is much less for BTL, so is its receiver threshold region, therefore noise margins are excellent. CASE 775-02 BTL offers low power consumption, low ground bounce, reduced EMI and ORDERING INFORMATION crosstalk, low capacitive loading, superior noise margin and short propaga- tion delays. This results in a high bandwidth, reliable backplane. MC74FXXXXAFN Plastic The MC74F3893A has four TTL outputs (Rn) on the receiver side with a LOGIC SYMBOL common Receive Enable input (RE). It has four data inputs (Dn) which are also TTL. These data inputs are NANDed with the Data Enable input (DE). The four 24 7 9 I/O pins (Bus side) are futurebus compatible, sink a minimum of 100 mA, and are designed to drive heavily loaded backplanes with load impedances as low 11 DE D0 D1 D2 D3 as 10 ohms. All outputs are designed to be glitch-free during power up and power down. 12 RE • Quad Backplane Transceiver I/O0 I/O1 I/O2 I/O3 R0 R1 R2 R3 • Drives Heavily Loaded Backplanes with Equivalent Load Impedances 18 17 15 14 3 5 8 10 Down to 10 ohms • Futurebus Drivers Sink 100 mA • Reduced Voltage Swing (1 Volt) Produces Less Noise and Reduces Power Consumption • High Speed Operation Enhances Performance of Backplane Buses and Facilitates Incident Wave Switching • Compatible with IEEE 896 and IEEE 1194.1 Futurebus Standards • Built-In Precision Band-Gap (BG) Reference Provides Accurate Re- ceiver Threshold and Improved Noise Immunity • Glitch-Free Power Up/Power Down Operation On All Outputs • Pin and Function Compatible with NSC DS3893A and Signetics 74F3893 • Separate Bus Ground Returns for Each Driver to Minimize Ground Noise • MOS and TTL Compatible High Impedance Inputs PINOUT: 20-LEAD PLCC (TOP VIEW) BUS I/O0 I/O1 GND I/O2 I/O3 18 17 16 15 14 BUS 19 13 BUS GND GND BG 20 12 RE GND VCC 1 11 DE D0 2 10 R3 R0 3 9 D3 4 56 78 D1 R1 LOGIC D2 R2 GND FAST AND LS TTL DATA 4-276

For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable device type. 2. All typical values are at VCC = 5.0 V, TA = + 25°C. 3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are prefer- able in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS tests should be performed last. FAST AND LS TTL DATA 4-278

SCHMITT TRIGGERS SN54/74LS13 DUAL GATE/HEX INVERTER SN54/74LS14 The SN54LS / 74LS13 and SN54LS / 74LS14 contain logic gates / inverters SCHMITT TRIGGERS which accept standard TTL input signals and provide standard TTL output DUAL GATE/ HEX INVERTER levels. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. Additionally, they have greater noise LOW POWER SCHOTTKY margin than conventional inverters. J SUFFIX Each circuit contains a Schmitt trigger followed by a Darlington level shifter CERAMIC and a phase splitter driving a TTL totem pole output. The Schmitt trigger uses CASE 632-08 positive feedback to effectively speed-up slow input transitions, and provide different input threshold voltages for positive and negative-going transitions. This hysteresis between the positive-going and negative-going input thresholds (typically 800 mV) is determined internally by resistor ratios and is essentially insensitive to temperature and supply voltage variations.
