74HC164AP

Sungine · Shift Registers · SOP-14

74HC164AP from Sungine, in a SOP-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, ANDed with B; if either A or B is low, new data entry is inhibited and the first flip-flop is set low on the next clock.
2 B input Serial data input B, ANDed with A; when one of A or B is high the other input enables data entry on the rising clock edge.
3 QA output Shift register output A (first stage).
4 QB output Shift register output B.
5 QC output Shift register output C.
6 QD output Shift register output D.
7 GND power_in Ground (0 V) reference; supply current through VCC or GND is limited to ±50 mA.
8 CLOCK input Clock input, data shifts one position on the low-to-high transition; input rise/fall time max 1000 ns at 2.0 V, 500 ns at 4.5 V, 400 ns at 6.0 V.
9 CLEAR input Active-low asynchronous clear input, a low level forces all outputs QA to QH low regardless of other inputs.
10 QE output Shift register output E.
11 QF output Shift register output F.
12 QG output Shift register output G.
13 QH output Shift register output H (last stage); output current limited to ±25 mA.
14 VCC power_in Positive supply voltage, recommended operating range 2 V to 6 V, absolute maximum -0.5 V to +7.0 V.
