MM74HC164M

onsemi · Shift Registers · SOIC-14

MM74HC164M from onsemi, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A input Serial data input A, gated with B: a LOW at either A or B inhibits new data entry and resets the first flip-flop at the next clock pulse.
2 B input Serial data input B, gated with A: a HIGH on one input enables the other to determine the state of the first flip-flop.
3 QA output Parallel output A, the first register stage.
4 QB output Parallel output B of the shift register.
5 QC output Parallel output C of the shift register.
6 QD output Parallel output D of the shift register.
7 GND power_in Ground, 0 V reference.
8 CLOCK input Clock input; data shifts on the positive-going (LOW-to-HIGH) transition.
9 CLEAR input Active-low asynchronous clear, independent of the clock; a LOW level resets all outputs LOW.
10 QE output Parallel output E of the shift register.
11 QF output Parallel output F of the shift register.
12 QG output Parallel output G of the shift register.
13 QH output Parallel output H, the last register stage.
14 VCC power_in Positive supply voltage, 2 V to 6 V recommended operating range.
