MC74F164

MC54/74F164 8-BIT SERIAL-IN, PARALLEL-OUT SHIFT REGISTER The MC54/74F164 is a high-speed 8-bit serial-in/parallel-out shift register. Serial data is entered through a 2-input AND gate synchronous with the LOW-to-HIGH transition of the clock. The device features an asynchronous Master Reset which clears the register, setting all outputs LOW independent of the clock. 8-BIT SERIAL-IN, PARALLEL-OUT SHIFT REGISTER FAST™ SHOTTKY TTL Typical Shift Frequency of 90 MHz Asynchronous Master Reset Gated Serial Data Input Fully Synchronous Data Transfers J SUFFIX CERAMIC CASE 632-08 1 14 CONNECTION DIAGRAM VCC 14 Q7 13 Q6 12 Q5 11 Q4 10 MR 9 CP 8 14 1 N SUFFIX PLASTIC CASE 646-06 1 A 2 B 3 Q0 4 Q1 5 Q2 6 Q3 7 GND 14 1 D SUFFIX SOIC CASE 751A-02 ORDERING INFORMATION MC54FXXXJ MC74FXXXN MC74FXXXD Inputs Operating Mode Reset (Clear) Shift MR L H H H H A X l l h h B X l h l h Q0 L L L L H Outputs Q1 –Q7 L–L q0–q6 q0–q6 q0–q6 q0–q6 1 2 8 A B CP MR Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 9 3 4 5 6 10 11 12 13 VCC = PIN 14 GND = PIN 7 Ceramic Plastic SOIC MODE SELECT TABLE LOGIC SYMBOL H(h) = HIGH Voltage Levels L(l) = LOW Voltage Levels X = Don’t Care qn = Lower case letters indicate the state of the referenced input or output one setup time prior to the LOW-to-HIGH clock transition.
