SN74AC596PWR from Texas Instruments, in a TSSOP-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 output Open-drain storage register output QB, with an open-drain output voltage range of 0 V to 6 V.
2 QC output Open-drain storage register output QC, with an open-drain output voltage range of 0 V to 6 V.
3 QD output Open-drain storage register output QD, with an open-drain output voltage range of 0 V to 6 V.
4 QE output Open-drain storage register output QE, with an open-drain output voltage range of 0 V to 6 V.
5 QF output Open-drain storage register output QF, with an open-drain output voltage range of 0 V to 6 V.
6 QG output Open-drain storage register output QG, with an open-drain output voltage range of 0 V to 6 V.
7 QH output Open-drain storage register output QH, with an open-drain output voltage range of 0 V to 6 V.
8 GND power_in Ground reference for the device.
9 QH' output Push-pull serial output QH' used for cascading to another shift register; push-pull output voltage is limited to VCC.
10 SRCLR input Active-low shift register clear input that clears the shift register directly.
11 SRCLK input Shift register clock input, triggered on the rising edge.
12 RCLK input Output (storage) register clock input, triggered on the rising edge.
13 OE input Active-low output enable input; when high, the outputs are placed in a high-impedance state without affecting internal register data.
14 SER input Serial data input to the 8-bit shift register.
15 QA output Open-drain storage register output QA, with an open-drain output voltage range of 0 V to 6 V.
16 VCC power_in Positive supply voltage, recommended range 1.5 V to 6 V.
