MC74HC597ADG from onsemi, in a SOIC-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 | B | input | Parallel data input B, stored in the input latch on the rising edge of Latch Clock. |
| 2 | C | input | Parallel data input C, stored in the input latch on the rising edge of Latch Clock. |
| 3 | D | input | Parallel data input D, stored in the input latch on the rising edge of Latch Clock. |
| 4 | E | input | Parallel data input E, stored in the input latch on the rising edge of Latch Clock. |
| 5 | F | input | Parallel data input F, stored in the input latch on the rising edge of Latch Clock. |
| 6 | G | input | Parallel data input G, stored in the input latch on the rising edge of Latch Clock. |
| 7 | H | input | Parallel data input H, stored in the input latch on the rising edge of Latch Clock. |
| 8 | GND | power_in | Ground reference pin for the device (PIN 8 = GND). |
| 9 | QH | output | Serial data output from the last stage of the shift register. |
| 10 | Reset | input | Asynchronous active-low input that resets the shift register to low without changing the input latch data. |
| 11 | Shift Clock | input | Serial shift register clock; a low-to-high transition shifts the serial input SA into the register and shifts stage H out to QH. |
| 12 | Latch Clock | input | A low-to-high transition on this input loads the parallel data on inputs A to H into the input latch. |
| 13 | Serial Shift/Parallel Load | input | Shift register mode control: a high level enables serial shifting, while a low level loads parallel data from the input latch and inhibits serial shifting. |
| 14 | SA | input | Serial data input that is shifted into the shift register on the rising Shift Clock edge only when Serial Shift/Parallel Load is high and is ignored when it is low. |
| 15 | A | input | Parallel data input A, stored in the input latch on the rising edge of Latch Clock. |
| 16 | VCC | power_in | Positive supply pin (PIN 16 = VCC); the device operates from 2.0 V to 6.0 V referenced to GND. |
