SN74HC595N from Texas Instruments, in a DIP-16. 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 | QB | tri_state | Output bit B of 8-bit shift register; tri-state output with ±6mA drive capability at 5V. |
| 2 | QC | tri_state | Output bit C of 8-bit shift register; tri-state output with ±6mA drive capability at 5V. |
| 3 | QD | tri_state | Output bit D of 8-bit shift register; tri-state output with ±6mA drive capability at 5V. |
| 4 | QE | tri_state | Output bit E of 8-bit shift register; tri-state output with ±6mA drive capability at 5V. |
| 5 | QF | tri_state | Output bit F of 8-bit shift register; tri-state output with ±6mA drive capability at 5V. |
| 6 | QG | tri_state | Output bit G of 8-bit shift register; tri-state output with ±6mA drive capability at 5V. |
| 7 | QH | tri_state | Output bit H of 8-bit shift register; tri-state output with ±6mA drive capability at 5V. |
| 8 | GND | power_in | Ground reference; power return and signal ground. |
| 9 | QH' | tri_state | Serial output from shift register; tri-state output for cascading multiple 74HC595 devices. |
| 10 | SRCLR | input | Shift register clear input (active low); immediately clears all bits when held low. |
| 11 | SRCLK | input | Shift register clock input (positive edge triggered); shifts data from SER into the first stage on rising edge. |
| 12 | RCLK | input | Storage register clock input (positive edge triggered); transfers shift register data to output register on rising edge. |
| 13 | OE | input | Output enable input (active low); places all outputs into high-impedance when held high. |
| 14 | SER | input | Serial data input; data is shifted into the first stage of shift register on SRCLK rising edge. |
| 15 | QA | tri_state | Output bit A of 8-bit shift register; tri-state output with ±6mA drive capability at 5V. |
| 16 | VCC | power_in | Positive power supply; device operates from 2V to 6V with typical ICC of 80μA maximum. |
