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 |
