SN74CBTLV3253PWR

Texas Instruments · Analog Switches, Multiplexers · TSSOP-16

SN74CBTLV3253PWR from Texas Instruments, in a TSSOP-16. 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 Output Enable 1, active-low; when high, channel 1 multiplexer is disabled.
2 S1 input Select input 1; with S0 controls which B port (B1-B4) connects to A port when OE is low.
3 1B4 bidirectional Channel 1 I/O port 4; bidirectional switch port selectable via S0, S1 inputs.
4 1B3 bidirectional Channel 1 I/O port 3; bidirectional switch port selectable via S0, S1 inputs.
5 1B2 bidirectional Channel 1 I/O port 2; bidirectional switch port selectable via S0, S1 inputs.
6 1B1 bidirectional Channel 1 I/O port 1; bidirectional switch port selectable via S0, S1 inputs.
7 1A bidirectional Channel 1 common port; bidirectional switch connecting to selected 1Bx based on S1, S0 when 1OE is low.
8 GND power_in Ground reference; 0V power supply return.
9 2A bidirectional Channel 2 common port; bidirectional switch connecting to selected 2Bx based on S1, S0 when 2OE is low.
10 2B1 bidirectional Channel 2 I/O port 1; bidirectional switch port selectable via S0, S1 inputs.
11 2B2 bidirectional Channel 2 I/O port 2; bidirectional switch port selectable via S0, S1 inputs.
12 2B3 bidirectional Channel 2 I/O port 3; bidirectional switch port selectable via S0, S1 inputs.
13 2B4 bidirectional Channel 2 I/O port 4; bidirectional switch port selectable via S0, S1 inputs.
14 S0 input Select input 0; with S1 controls which B port (B1-B4) connects to A port when OE is low.
15 2OE input Output Enable 2, active-low; when high, channel 2 multiplexer is disabled.
16 VCC power_in Positive power supply; 2.3V to 3.6V recommended operating range per Section 5.3.
