Texas Instruments · Signal Switches, Multiplexers, Decoders · TSSOP-16

CD74HC237PWR 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 A0 input Binary address input 0; used with A1, A2 to select one of eight outputs.
2 A1 input Binary address input 1; used with A0, A2 to select one of eight outputs.
3 A2 input Binary address input 2; used with A0, A1 to select one of eight outputs.
4 LE input Latch Enable input; active high to latch address inputs and isolate outputs from select-input changes.
5 OE1 input Output Enable input 1; used with OE0 to enable or disable outputs for cascading and demultiplexing.
6 OE0 input Output Enable input 0; used with OE1 to enable or disable outputs for cascading and demultiplexing.
7 Y7 output Active-high output 7; selected when A2=1, A1=1, A0=1.
8 GND power_in Ground; negative power supply.
9 Y6 output Active-high output 6; selected when A2=1, A1=1, A0=0.
10 Y5 output Active-high output 5; selected when A2=1, A1=0, A0=1.
11 Y4 output Active-high output 4; selected when A2=1, A1=0, A0=0.
12 Y3 output Active-high output 3; selected when A2=0, A1=1, A0=1.
13 Y2 output Active-high output 2; selected when A2=0, A1=1, A0=0.
14 Y1 output Active-high output 1; selected when A2=0, A1=0, A0=1.
15 Y0 output Active-high output 0; selected when A2=0, A1=0, A0=0.
16 VCC power_in Positive power supply voltage; 2V to 6V for HC type.
