CD74HC597E

Texas Instruments · Shifting Register · PDIP-16

CD74HC597E from Texas Instruments, in a PDIP-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 D1 input Parallel data input D1 to the 8-bit input storage flip-flops, which are loaded on the rising edge of STCP.
2 D2 input Parallel data input D2 to the 8-bit input storage flip-flops, which are loaded on the rising edge of STCP.
3 D3 input Parallel data input D3 to the 8-bit input storage flip-flops, which are loaded on the rising edge of STCP.
4 D4 input Parallel data input D4 to the 8-bit input storage flip-flops, which are loaded on the rising edge of STCP.
5 D5 input Parallel data input D5 to the 8-bit input storage flip-flops, which are loaded on the rising edge of STCP.
6 D6 input Parallel data input D6 to the 8-bit input storage flip-flops, which are loaded on the rising edge of STCP.
7 D7 input Parallel data input D7 to the 8-bit input storage flip-flops, which are loaded on the rising edge of STCP.
8 GND power_in Ground reference for the device.
9 Q7 output Serial data output from the last stage of the 8-bit shift register (Qn = Qn-1 on each SHCP rising edge).
10 MR input Active-low master reset input; when low (with PL high) it clears the shift register.
11 SHCP input Shift register clock input; the shift register shifts on the low-to-high transition when PL is high and MR is high.
12 STCP input Storage register clock input; a low-to-high transition loads the Dn data into the input flip-flops.
13 PL input Active-low asynchronous parallel load input; when low it shifts the parallel stored data into the shift register.
14 DS input Serial data input to the first shift register stage (Q0), shifted in on the SHCP rising edge.
15 D0 input Parallel data input D0 to the 8-bit input storage flip-flops, which are loaded on the rising edge of STCP.
16 VCC power_in Positive supply voltage; 2 V to 6 V for HC types, as stated in the operating conditions.
