SN74HC652DWR

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOIC-24

SN74HC652DWR from Texas Instruments, in a SOIC-24. 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 CLKAB input Clock input for the A-bus internal D-type flip-flops; data on the A or B bus is stored on each low-to-high transition of this clock, regardless of the select or output-control terminals.
2 SAB input A-bus select control: a low level selects real-time data transfer and a high level selects stored data.
3 OEAB input Output enable for the A-bus outputs; it should be tied to GND through a pulldown resistor to ensure the high-impedance state during power up or power down.
4 A1 bidirectional A-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
5 A2 bidirectional A-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
6 A3 bidirectional A-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
7 A4 bidirectional A-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
8 A5 bidirectional A-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
9 A6 bidirectional A-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
10 A7 bidirectional A-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
11 A8 bidirectional A-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
12 GND power_in Device ground; all unused inputs must be held at VCC or GND to ensure proper device operation.
13 B8 bidirectional B-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
14 B7 bidirectional B-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
15 B6 bidirectional B-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
16 B5 bidirectional B-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
17 B4 bidirectional B-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
18 B3 bidirectional B-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
19 B2 bidirectional B-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
20 B1 bidirectional B-bus data input/output, 3-state output capable of driving up to 15 LSTTL loads.
21 OEBA input Output enable for the B-bus outputs; it should be tied to VCC through a pullup resistor to ensure the high-impedance state during power up or power down.
22 SBA input B-bus select control: a low level selects real-time data transfer and a high level selects stored data.
23 CLKBA input Clock input for the B-bus internal D-type flip-flops; data on the A or B bus is stored on each low-to-high transition of this clock, regardless of the select or output-control terminals.
24 VCC power_in Supply voltage, recommended operating range 2 V to 6 V; absolute maximum 7 V.
