SN74LV164ADBR

Texas Instruments · Shift Registers · SSOP-14-208mil

SN74LV164ADBR from Texas Instruments, in a SSOP-14-208mil. 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 input A; NAND-gated with input B to control data entry into the shift register
2 B input Serial input B; NAND-gated with input A to control data entry into the shift register
3 QA output Parallel output A; first stage of 8-bit shift register
4 QB output Parallel output B; second stage of 8-bit shift register
5 QC output Parallel output C; third stage of 8-bit shift register
6 QD output Parallel output D; fourth stage of 8-bit shift register
7 GND power_in Ground pin; reference voltage for logic levels
8 CLK input Storage clock input; data shifts on low-to-high transition
9 CLR input Asynchronous clear input; active low resets all Q outputs to logic low
10 QE output Parallel output E; fifth stage of 8-bit shift register
11 QF output Parallel output F; sixth stage of 8-bit shift register
12 QG output Parallel output G; seventh stage of 8-bit shift register
13 QH output Parallel output H; eighth stage of 8-bit shift register
14 VCC power_in Power supply pin; 2V to 5.5V recommended operating range
