Texas Instruments · Signal Switches, Multiplexers, Decoders · SSOP-24-150mil

SN74CB3T3384DBQR from Texas Instruments, in a SSOP-24-150mil. 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 1OE input Active-low output enable for the first 5-bit bus switch; low connects 1A to 1B, high gives high-impedance (tie to VCC via pullup for power up/down).
2 1B1 bidirectional Bus switch 1 B-port channel 1 data I/O, supports 0 to 5.5-V signaling.
3 1A1 bidirectional Bus switch 1 A-port channel 1 data I/O, supports 0 to 5.5-V signaling.
4 1A2 bidirectional Bus switch 1 A-port channel 2 data I/O, supports 0 to 5.5-V signaling.
5 1B2 bidirectional Bus switch 1 B-port channel 2 data I/O, supports 0 to 5.5-V signaling.
6 1B3 bidirectional Bus switch 1 B-port channel 3 data I/O, supports 0 to 5.5-V signaling.
7 1A3 bidirectional Bus switch 1 A-port channel 3 data I/O, supports 0 to 5.5-V signaling.
8 1A4 bidirectional Bus switch 1 A-port channel 4 data I/O, supports 0 to 5.5-V signaling.
9 1B4 bidirectional Bus switch 1 B-port channel 4 data I/O, supports 0 to 5.5-V signaling.
10 1B5 bidirectional Bus switch 1 B-port channel 5 data I/O, supports 0 to 5.5-V signaling.
11 1A5 bidirectional Bus switch 1 A-port channel 5 data I/O, supports 0 to 5.5-V signaling.
12 GND power_in Ground.
13 2OE input Active-low output enable for the second 5-bit bus switch; low connects 2A to 2B, high gives high-impedance (tie to VCC via pullup for power up/down).
14 2A1 bidirectional Bus switch 2 A-port channel 1 data I/O, supports 0 to 5.5-V signaling.
15 2B1 bidirectional Bus switch 2 B-port channel 1 data I/O, supports 0 to 5.5-V signaling.
16 2B2 bidirectional Bus switch 2 B-port channel 2 data I/O, supports 0 to 5.5-V signaling.
17 2A2 bidirectional Bus switch 2 A-port channel 2 data I/O, supports 0 to 5.5-V signaling.
18 2A3 bidirectional Bus switch 2 A-port channel 3 data I/O, supports 0 to 5.5-V signaling.
19 2B3 bidirectional Bus switch 2 B-port channel 3 data I/O, supports 0 to 5.5-V signaling.
20 2B4 bidirectional Bus switch 2 B-port channel 4 data I/O, supports 0 to 5.5-V signaling.
21 2A4 bidirectional Bus switch 2 A-port channel 4 data I/O, supports 0 to 5.5-V signaling.
22 2A5 bidirectional Bus switch 2 A-port channel 5 data I/O, supports 0 to 5.5-V signaling.
23 2B5 bidirectional Bus switch 2 B-port channel 5 data I/O, supports 0 to 5.5-V signaling.
24 VCC power_in Supply voltage, 2.3 V to 3.6 V operating range; output voltage translation tracks VCC.
