Texas Instruments · Analog Switches, Multiplexers · TSSOP-24

SN74CB3T3384PWR from Texas Instruments, in a TSSOP-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 1OE input Active-low output enable for the first 5-bit bus switch: when low the 1A and 1B ports are connected, and when high they are in high-impedance; tie to VCC through a pullup resistor so the high-impedance state holds during power up or power down.
2 1B1 bidirectional B-side data port 1 of the first 5-bit switch, connected to 1A1 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
3 1A1 bidirectional A-side data port 1 of the first 5-bit switch, connected to 1B1 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
4 1A2 bidirectional A-side data port 2 of the first 5-bit switch, connected to 1B2 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
5 1B2 bidirectional B-side data port 2 of the first 5-bit switch, connected to 1A2 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
6 1B3 bidirectional B-side data port 3 of the first 5-bit switch, connected to 1A3 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
7 1A3 bidirectional A-side data port 3 of the first 5-bit switch, connected to 1B3 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
8 1A4 bidirectional A-side data port 4 of the first 5-bit switch, connected to 1B4 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
9 1B4 bidirectional B-side data port 4 of the first 5-bit switch, connected to 1A4 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
10 1B5 bidirectional B-side data port 5 of the first 5-bit switch, connected to 1A5 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
11 1A5 bidirectional A-side data port 5 of the first 5-bit switch, connected to 1B5 when 1OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
12 GND power_in Ground reference for the device; all voltages are referenced to ground.
13 2OE input Active-low output enable for the second 5-bit bus switch: when low the 2A and 2B ports are connected, and when high they are in high-impedance; tie to VCC through a pullup resistor so the high-impedance state holds during power up or power down.
14 2A1 bidirectional A-side data port 1 of the second 5-bit switch, connected to 2B1 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
15 2B1 bidirectional B-side data port 1 of the second 5-bit switch, connected to 2A1 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
16 2B2 bidirectional B-side data port 2 of the second 5-bit switch, connected to 2A2 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
17 2A2 bidirectional A-side data port 2 of the second 5-bit switch, connected to 2B2 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
18 2A3 bidirectional A-side data port 3 of the second 5-bit switch, connected to 2B3 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
19 2B3 bidirectional B-side data port 3 of the second 5-bit switch, connected to 2A3 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
20 2B4 bidirectional B-side data port 4 of the second 5-bit switch, connected to 2A4 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
21 2A4 bidirectional A-side data port 4 of the second 5-bit switch, connected to 2B4 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
22 2A5 bidirectional A-side data port 5 of the second 5-bit switch, connected to 2B5 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
23 2B5 bidirectional B-side data port 5 of the second 5-bit switch, connected to 2A5 when 2OE is low; 5-V tolerant, with data I/O rated 0 to 5.5 V.
24 VCC power_in Supply voltage, recommended operating range 2.3 V to 3.6 V, with ICC of 40 µA max; the data I/O output high level tracks VCC.
