CD74HC238PWR

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

CD74HC238PWR 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 the 3-to-8 decoder
2 A1 input Address select input 1 for the 3-to-8 decoder
3 A2 input Address select input 2 for the 3-to-8 decoder
4 G0 input Output strobe 0, active low; all outputs driven low when G0 is high
5 G1 input Output strobe 1, active low; all outputs driven low when G1 is high
6 G2 input Output strobe 2; all outputs driven low when G2 is low
7 Y7 output Decoder output; high when address A2:A0 = 111 (binary) and strobes enable, otherwise low
8 GND power_in Ground connection
9 Y6 output Decoder output; high when address A2:A0 = 110 (binary) and strobes enable, otherwise low
10 Y5 output Decoder output; high when address A2:A0 = 101 (binary) and strobes enable, otherwise low
11 Y4 output Decoder output; high when address A2:A0 = 100 (binary) and strobes enable, otherwise low
12 Y3 output Decoder output; high when address A2:A0 = 011 (binary) and strobes enable, otherwise low
13 Y2 output Decoder output; high when address A2:A0 = 010 (binary) and strobes enable, otherwise low
14 Y1 output Decoder output; high when address A2:A0 = 001 (binary) and strobes enable, otherwise low
15 Y0 output Decoder output; high when address A2:A0 = 000 (binary) and strobes enable, otherwise low
16 VCC power_in Positive power supply voltage, 2 V to 6 V for HC type per recommended operating conditions
