SCHMITT TRIGGERS DUAL 4-INPUT MC54/74F13 MC54/74F14 NAND/HEX INVERTERS SCHMITT TRIGGERS The MC54/74F13 and MC54/74F14 contain logic gates/inverters which ac- DUAL 4-INPUT cept standard TTL input signals and provide standard TTL output levels. They are capable of transforming slowly changing input signals into sharply de- NAND/HEX INVERTERS fined, jitter-free output signals. Additionally, they have greater noise margin than conventional inverters. FAST™ SCHOTTKY TTL Each circuit contains a Schmitt trigger followed by a Darlington level shifter J SUFFIX and a phase splitter driving a TTL totem pole output. The Schmitt trigger uses CERAMIC positive feedback to effectively speed up slow input transitions and provide CASE 632-08 different input threshold voltages for positive and negative-going transitions. This hysteresis between the positive-going and negative-going input thresh- olds (typically 800 mV) is determined internally by resistor ratios and is essen- tially insensitive to temperature and supply voltage variations.

Information at the input is transferred to the outputs on the positive edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive-going pulse. After the Clock Pulse input threshold voltage has been passed, the Data input is locked out and information present will not be transferred to the outputs until the next rising edge of the Clock Pulse input. • ESD > 4000 Volts CONNECTION DIAGRAM J SUFFIX CERAMIC VCC CD2 D2 CP2 SD2 Q2 Q2 CASE 632-08 14 13 12 11 10 9 8 14 1 D1 CD1 Q1 CP2 SD2 Q2 N SUFFIX CP1 SD1 Q1 D2 CD2 Q2 PLASTIC CASE 646-06 14 1234567 1 CD1 D1 CP1 SD1 Q1 Q1 GND 14 D SUFFIX 1 SOIC CASE 751A-02 FUNCTION TABLE (Each Half) Input Outputs ORDERING INFORMATION @ tn @ tn + 1 MC54FXXJ Ceramic D QQ MC74FXXN Plastic MC74FXXD SOIC L LH H HL LOGIC SYMBOL Asynchronous Inputs: 4 10 LOW Input to SD sets Q to HIGH level LOW Input to CD sets Q to LOW level Clear and Set are independent of clock Simultaneous LOW on CD and SD makes both Q and Q HIGH H = HIGH Voltage Level 2 D1SD1Q1 5 12 D2SD2Q2 9 L = LOW Voltage Level 3 CP1 11 CP2 tn = Bit time before clock pulse Q1 6 Q2 tn + 1 = Bit time after clock pulse CD1 CD2 8 1 13 VCC = PIN 14 GND = PIN 7 FAST AND LS TTL DATA 4-33

MC54/74F85 4-BIT MAGNITUDE COMPARATOR 4-BIT MAGNITUDE COMPARATOR FAST™ SCHOTTKY TTL The MC54/74F85 is a 4-Bit Magnitude Comparator which compares two 4-Bit words (A0-A3, B0-B3), A3, B3being the most significantinputs. Operation J SUFFIX is not restricted to binary codes; the device will work with any monotonic code. CERAMIC Three Outputs are provided: “A greater than B” (0A > B), “A less than B” (0A CASE 620-09 < B), “A equal to B” (0A = B). Three Expander Inputs, IA > B, IA < B, IA = B, allow cascading without external gates. For proper compare operation, the Expan- 16 der Inputs to the least significant position must be connected as follows: IA < 1 B = IA > B = L, IA = B = H. For serial (ripple) expansion the 0A > B, 0A < B Outputs are connected respectively to the IA > B and IA = B inputs of the next most sig- nificant comparator, as shown in Figure 1.

MC74F112 DUAL JK NEGATIVE DUAL JK NEGATIVE EDGE-TRIGGERED FLIP-FLOP EDGE-TRIGGERED FLIP-FLOP FAST™ SCHOTTKY TTL The MC74F112 contains two independent, high-speed JK flip-flops with Di- rect Set and Clear inputs. Synchronous state changes are initiated by the fal- ling edge of the clock. Triggering occurs at a voltage level of the clock and is not directly related to the transition time. The J and K inputs can change when the clock is in either state without affecting the flip-flop, provided that they are in the desired state during the recommended setup and hold times relative to the falling edge of the clock. A LOW signal on SD or CD prevents clocking and forces Q or Q HIGH, respectively. Simultaneous LOW signals on SD and CD force both Q and Q HIGH.

MC54/74F132 QUAD 2-INPUT NAND QUAD 2-INPUT NAND SCHMITT TRIGGER SCHMITT TRIGGER The MC54/74F132 contains four 2-input NAND gates which accept stan- FAST™ SHOTTKY TTL dard TTL input signals and provide standard TTL output levels. They are ca- pable of transforming slowly changing input signals into sharply defined, jit- J SUFFIX ter-free output signals. In addition, they have greater noise margin than CERAMIC conventional NAND gates. CASE 632-08 Each circuit contains a 2-input Schmitt trigger followed by a Darlington level 14 shifter and a phase splitter driving a TTL totem-pole output. The Schmitt trig- 1 ger uses positive feedback to effectively speed up slow input transitions and provide different input threshold voltages for positive and negative-going tran- sitions. This hysteresis between the positive-going and negative-going input threshold (typically 800 mV) is determined by resistor ratios and is essentially insensitive to temperature and supply voltage variations.
