Nexperia · Shift Registers · SOIC-16

74AHC595D from Nexperia, 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 Q1 tri_state Parallel data output Q1 of the storage register; it is in the high-impedance OFF-state when OE is HIGH.
2 Q2 tri_state Parallel data output Q2 of the storage register; it is in the high-impedance OFF-state when OE is HIGH.
3 Q3 tri_state Parallel data output Q3 of the storage register; it is in the high-impedance OFF-state when OE is HIGH.
4 Q4 tri_state Parallel data output Q4 of the storage register; it is in the high-impedance OFF-state when OE is HIGH.
5 Q5 tri_state Parallel data output Q5 of the storage register; it is in the high-impedance OFF-state when OE is HIGH.
6 Q6 tri_state Parallel data output Q6 of the storage register; it is in the high-impedance OFF-state when OE is HIGH.
7 Q7 tri_state Parallel data output Q7 of the storage register; it is in the high-impedance OFF-state when OE is HIGH.
8 GND power_in Ground (0 V) reference for all voltages on the device.
9 Q7S output Serial data output Q7S, which passes the shift register stage 7 state for cascading to another device.
10 MR input Asynchronous master reset input, active LOW; a LOW level resets the shift register.
11 SHCP input Shift register clock input; data is shifted on the LOW-to-HIGH transition of SHCP.
12 STCP input Storage register clock input; data is transferred to the storage register on the LOW-to-HIGH transition of STCP.
13 OE input Output enable input, active LOW; a HIGH level forces the Qn outputs into the high-impedance OFF-state.
14 DS input Serial data input to the 8-bit shift register.
15 Q0 tri_state Parallel data output Q0 of the storage register; it is in the high-impedance OFF-state when OE is HIGH.
16 VCC power_in Supply voltage, 2.0 V to 5.5 V for the 74AHC595 (Table 5).
