CY74FCT245CTSOC

Texas Instruments · Latches · SOIC-20-300mil

CY74FCT245CTSOC from Texas Instruments, in a SOIC-20-300mil. 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 T/R input Transmit/receive control input; high enables transmission A to B, low enables reception B to A
2 A0 bidirectional A-port bit 0 noninverting bidirectional buffer with 3-state output
3 A1 bidirectional A-port bit 1 noninverting bidirectional buffer with 3-state output
4 A2 bidirectional A-port bit 2 noninverting bidirectional buffer with 3-state output
5 A3 bidirectional A-port bit 3 noninverting bidirectional buffer with 3-state output
6 A4 bidirectional A-port bit 4 noninverting bidirectional buffer with 3-state output
7 A5 bidirectional A-port bit 5 noninverting bidirectional buffer with 3-state output
8 A6 bidirectional A-port bit 6 noninverting bidirectional buffer with 3-state output
9 A7 bidirectional A-port bit 7 noninverting bidirectional buffer with 3-state output
10 GND power_in Ground (0V reference potential)
11 B7 bidirectional B-port bit 7 noninverting bidirectional buffer with 3-state output
12 B6 bidirectional B-port bit 6 noninverting bidirectional buffer with 3-state output
13 B5 bidirectional B-port bit 5 noninverting bidirectional buffer with 3-state output
14 B4 bidirectional B-port bit 4 noninverting bidirectional buffer with 3-state output
15 B3 bidirectional B-port bit 3 noninverting bidirectional buffer with 3-state output
16 B2 bidirectional B-port bit 2 noninverting bidirectional buffer with 3-state output
17 B1 bidirectional B-port bit 1 noninverting bidirectional buffer with 3-state output
18 B0 bidirectional B-port bit 0 noninverting bidirectional buffer with 3-state output
19 OE input Output enable control input; high places all A and B ports in high-impedance state
20 VCC power_in Positive power supply voltage, 4.75V to 5.25V nominal 5V for CY74FCT245CT
