Texas Instruments · Signal Switches, Multiplexers, Decoders · TSSOP-24

SN74CBT3384APWR 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 switch; low connects 1A to 1B, high opens the switch (high impedance).
2 1B1 bidirectional Port B bit 1 of the first 5-bit switch, connected to 1A1 through a 5-Ω switch when 1OE is low.
3 1A1 bidirectional Port A bit 1 of the first 5-bit switch, connected to 1B1 when 1OE is low.
4 1A2 bidirectional Port A bit 2 of the first 5-bit switch, connected to 1B2 when 1OE is low.
5 1B2 bidirectional Port B bit 2 of the first 5-bit switch, connected to 1A2 when 1OE is low.
6 1B3 bidirectional Port B bit 3 of the first 5-bit switch, connected to 1A3 when 1OE is low.
7 1A3 bidirectional Port A bit 3 of the first 5-bit switch, connected to 1B3 when 1OE is low.
8 1A4 bidirectional Port A bit 4 of the first 5-bit switch, connected to 1B4 when 1OE is low.
9 1B4 bidirectional Port B bit 4 of the first 5-bit switch, connected to 1A4 when 1OE is low.
10 1B5 bidirectional Port B bit 5 of the first 5-bit switch, connected to 1A5 when 1OE is low.
11 1A5 bidirectional Port A bit 5 of the first 5-bit switch, connected to 1B5 when 1OE is low.
12 GND power_in Ground.
13 2OE input Active-low output enable for the second 5-bit switch; low connects 2A to 2B, high opens the switch (high impedance).
14 2A1 bidirectional Port A bit 1 of the second 5-bit switch, connected to 2B1 when 2OE is low.
15 2B1 bidirectional Port B bit 1 of the second 5-bit switch, connected to 2A1 when 2OE is low.
16 2B2 bidirectional Port B bit 2 of the second 5-bit switch, connected to 2A2 when 2OE is low.
17 2A2 bidirectional Port A bit 2 of the second 5-bit switch, connected to 2B2 when 2OE is low.
18 2A3 bidirectional Port A bit 3 of the second 5-bit switch, connected to 2B3 when 2OE is low.
19 2B3 bidirectional Port B bit 3 of the second 5-bit switch, connected to 2A3 when 2OE is low.
20 2B4 bidirectional Port B bit 4 of the second 5-bit switch, connected to 2A4 when 2OE is low.
21 2A4 bidirectional Port A bit 4 of the second 5-bit switch, connected to 2B4 when 2OE is low.
22 2A5 bidirectional Port A bit 5 of the second 5-bit switch, connected to 2B5 when 2OE is low.
23 2B5 bidirectional Port B bit 5 of the second 5-bit switch, connected to 2A5 when 2OE is low.
24 VCC power_in Supply voltage, recommended 4 V to 5.5 V (absolute maximum −0.5 V to 7 V).
