CD74HC245M96

Texas Instruments · Latches · SOIC-20-300mil

CD74HC245M96 from Texas Instruments, in a SOIC-20-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	DIR	input	Direction control input. When DIR = L, data flows from the B bus to the A bus; when DIR = H, data flows from the A bus to the B bus. CMOS/LSTTL-compatible logic input.
2	A0	bidirectional	Bidirectional data I/O, channel 0 of the A-side bus. Acts as an input when DIR = H (data flows to B0) and as a 3-state output when DIR = L. High-Z when OE = H.
3	A1	bidirectional	Bidirectional data I/O, channel 1 of the A-side bus. Paired with B1 through the internal transceiver.
4	A2	bidirectional	Bidirectional data I/O, channel 2 of the A-side bus. Paired with B2 through the internal transceiver.
5	A3	bidirectional	Bidirectional data I/O, channel 3 of the A-side bus. Paired with B3 through the internal transceiver.
6	A4	bidirectional	Bidirectional data I/O, channel 4 of the A-side bus. Paired with B4 through the internal transceiver.
7	A5	bidirectional	Bidirectional data I/O, channel 5 of the A-side bus. Paired with B5 through the internal transceiver.
8	A6	bidirectional	Bidirectional data I/O, channel 6 of the A-side bus. Paired with B6 through the internal transceiver.
9	A7	bidirectional	Bidirectional data I/O, channel 7 of the A-side bus. Paired with B7 through the internal transceiver.
10	GND	power_in	Ground reference (0 V). Tie to system ground.
11	B7	bidirectional	Bidirectional data I/O, channel 7 of the B-side bus. Paired with A7 through the internal transceiver.
12	B6	bidirectional	Bidirectional data I/O, channel 6 of the B-side bus. Paired with A6 through the internal transceiver.
13	B5	bidirectional	Bidirectional data I/O, channel 5 of the B-side bus. Paired with A5 through the internal transceiver.
14	B4	bidirectional	Bidirectional data I/O, channel 4 of the B-side bus. Paired with A4 through the internal transceiver.
15	B3	bidirectional	Bidirectional data I/O, channel 3 of the B-side bus. Paired with A3 through the internal transceiver.
16	B2	bidirectional	Bidirectional data I/O, channel 2 of the B-side bus. Paired with A2 through the internal transceiver.
17	B1	bidirectional	Bidirectional data I/O, channel 1 of the B-side bus. Paired with A1 through the internal transceiver.
18	B0	bidirectional	Bidirectional data I/O, channel 0 of the B-side bus. Paired with A0 through the internal transceiver.
19	OE	input	Active-low output enable. When OE = L, the transceiver is enabled and drives in the direction set by DIR. When OE = H, both A and B I/O ports are placed in the high-impedance (isolation) state.
20	VCC	power_in	Positive supply. HC types: 2 V to 6 V; HCT types: 4.5 V to 5.5 V. Decouple with a 0.1 µF (and optional 1 µF) bypass capacitor as close to the pin as possible.
