SN74CBTLV3383DBQR

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

SN74CBTLV3383DBQR 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 BE input Active-low enable; when high, disables all switches; when low, BX controls signal path selection.
2 1B1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
3 1A1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
4 1A2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
5 1B2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
6 2B1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
7 2A1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
8 2A2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
9 2B2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
10 3B1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
11 3A1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
12 GND power_in Ground (0V) reference for power supply.
13 BX input Bus exchange select; high exchanges signal pairs, low connects directly when BE is low.
14 3A2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
15 3B2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
16 4B1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
17 4A1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
18 4A2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
19 4B2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
20 5B1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
21 5A1 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
22 5A2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
23 5B2 bidirectional Bidirectional signal path; input or output with 5Ω typical on-state resistance.
24 VCC power_out Positive power supply; operating range 2.3V to 3.6V.
