SN74HCS238DR

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

SN74HCS238DR from Texas Instruments, in a SOIC-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 Address input 0; schmitt-trigger input for 3-to-8 decoder binary selection.
2 A1 input Address input 1; schmitt-trigger input for 3-to-8 decoder binary selection.
3 A2 input Address input 2; schmitt-trigger input for 3-to-8 decoder binary selection.
4 G0 input Active-low strobe input; all outputs forced low when this input is high.
5 G1 input Active-low strobe input; all outputs forced low when this input is high.
6 G2 input Strobe input; all outputs forced low when this input is low.
7 Y7 output Output 7; normally low, transitions high when address selects this output and device is enabled.
8 GND power_in Ground connection.
9 Y6 output Output 6; normally low, transitions high when address selects this output and device is enabled.
10 Y5 output Output 5; normally low, transitions high when address selects this output and device is enabled.
11 Y4 output Output 4; normally low, transitions high when address selects this output and device is enabled.
12 Y3 output Output 3; normally low, transitions high when address selects this output and device is enabled.
