MC54F164

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. Typical Shift Frequency of 90 MHz Asynchronous Master Reset Gated Serial Data Input Fully Synchronous Data Transfers CONNECTION DIAGRAM VCC Q7 Q6 Q5 Q4 MR CP 14 13 12 11 10 9 8 1234567 A B Q0 Q1 Q2 Q3 GND MODE SELECT TABLE Inputs Outputs Operating Mode MR A B Q0 Q1 –Q7 Reset (Clear) L XX L L–L Shift H l l L q0–q6 H lh L q0–q6 H h l L q0–q6 H hh H q0–q6 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.
