SN74HC595DR from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | QB | tri_state | Parallel 3-state output B from the storage register. Drives up to 15 LSTTL loads (±6 mA at 5 V). High-impedance when OE is high. |
| 2 | QC | tri_state | Parallel 3-state output C from the storage register. Drives up to 15 LSTTL loads (±6 mA at 5 V). High-impedance when OE is high. |
| 3 | QD | tri_state | Parallel 3-state output D from the storage register. Drives up to 15 LSTTL loads (±6 mA at 5 V). High-impedance when OE is high. |
| 4 | QE | tri_state | Parallel 3-state output E from the storage register. Drives up to 15 LSTTL loads (±6 mA at 5 V). High-impedance when OE is high. |
| 5 | QF | tri_state | Parallel 3-state output F from the storage register. Drives up to 15 LSTTL loads (±6 mA at 5 V). High-impedance when OE is high. |
| 6 | QG | tri_state | Parallel 3-state output G from the storage register. Drives up to 15 LSTTL loads (±6 mA at 5 V). High-impedance when OE is high. |
| 7 | QH | tri_state | Parallel 3-state output H from the storage register. Drives up to 15 LSTTL loads (±6 mA at 5 V). High-impedance when OE is high. |
| 8 | GND | power_in | Ground reference (0 V) for the device. |
| 9 | QH' | output | Serial output from the shift register (not 3-stated). Used for cascading additional SN74HC595 devices - connect to the SER input of the next stage. Reflects the shift-register QH bit. |
| 10 | SRCLR | input | Active-low shift-register clear input. When low, asynchronously clears the 8-bit shift register. Does not affect the storage register. |
| 11 | SRCLK | input | Shift-register clock input. Serial data on SER is shifted into the shift register on the rising edge. Max clock frequency ~25 MHz at 4.5 V. |
| 12 | RCLK | input | Storage-register (latch) clock input. On the rising edge, the shift-register contents are transferred to the 8-bit D-type storage register that drives QA-QH. |
| 13 | OE | input | Active-low output-enable input. When high, parallel outputs QA-QH are placed in the high-impedance state. Does not affect the storage register contents. |
| 14 | SER | input | Serial data input to the shift register. Sampled on the rising edge of SRCLK. Setup time 20 ns at 4.5 V. |
| 15 | QA | tri_state | Parallel 3-state output A from the storage register (LSB of output byte). Drives up to 15 LSTTL loads (±6 mA at 5 V). High-impedance when OE is high. |
| 16 | VCC | power_in | Positive supply voltage input. Operating range 2 V to 6 V (5 V nominal). Bypass locally with a 0.1 µF ceramic capacitor to GND. |
