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

SN74HCS138PWR 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 for 3:8 decoder output selection
2 A1 input Address select input 1 for 3:8 decoder output selection
3 A2 input Address select input 2 for 3:8 decoder output selection
4 G0 input Active low strobe input; all outputs forced high when G0 is high
5 G1 input Active low strobe input; all outputs forced high when G1 is high
6 G2 input Strobe input; all outputs forced high when G2 is low
7 Y7 output Decoder output 7; normally high, driven low when address and strobes select this output
8 GND power_in Ground
9 Y6 output Decoder output 6; normally high, driven low when address and strobes select this output
10 Y5 output Decoder output 5; normally high, driven low when address and strobes select this output
11 Y4 output Decoder output 4; normally high, driven low when address and strobes select this output
12 Y3 output Decoder output 3; normally high, driven low when address and strobes select this output
13 Y2 output Decoder output 2; normally high, driven low when address and strobes select this output
14 Y1 output Decoder output 1; normally high, driven low when address and strobes select this output
15 Y0 output Decoder output 0; normally high, driven low when address and strobes select this output
16 VCC power_in Positive supply voltage, 2 V to 6 V recommended operating range
