SN74HCS238PWR

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

SN74HCS238PWR 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 Address select input 0; 3-to-8 decoder address line with Schmitt-trigger, VI = 0 to VCC V
2 A1 input Address select input 1; 3-to-8 decoder address line with Schmitt-trigger, VI = 0 to VCC V
3 A2 input Address select input 2; 3-to-8 decoder address line with Schmitt-trigger, VI = 0 to VCC V
4 G0 input Strobe input, active-low; all Y outputs forced low when G0 is high, VI = 0 to VCC V
5 G1 input Strobe input, active-low; all Y outputs forced low when G1 is high, VI = 0 to VCC V
6 G2 input Strobe input for output enable; all Y outputs forced low when G2 is low, VI = 0 to VCC V
7 Y7 output Decoder output 7; active high when address selects this output and all strobes enable, VO = 0 to VCC V
8 GND power_in Ground; 0 V reference, continuous current through GND ±70 mA maximum
9 Y6 output Decoder output 6; active high when address selects this output and all strobes enable, VO = 0 to VCC V
10 Y5 output Decoder output 5; active high when address selects this output and all strobes enable, VO = 0 to VCC V
11 Y4 output Decoder output 4; active high when address selects this output and all strobes enable, VO = 0 to VCC V
12 Y3 output Decoder output 3; active high when address selects this output and all strobes enable, VO = 0 to VCC V
13 Y2 output Decoder output 2; active high when address selects this output and all strobes enable, VO = 0 to VCC V
14 Y1 output Decoder output 1; active high when address selects this output and all strobes enable, VO = 0 to VCC V
15 Y0 output Decoder output 0; active high when address selects this output and all strobes enable, VO = 0 to VCC V
16 VCC power_out Positive supply voltage; 2 V to 6 V recommended operating range, continuous current through VCC ±70 mA maximum
