CD74HC238M96 from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Address input bit 0. Binary-weighted select input; combined with A1 and A2 selects one of eight outputs Y0-Y7. CMOS input, VIH ≥ 0.7·VCC, VIL ≤ 0.2·VCC.
2 A1 input Address input bit 1. Binary-weighted select input; combined with A0 and A2 selects one of eight outputs Y0-Y7. CMOS input, VIH ≥ 0.7·VCC, VIL ≤ 0.2·VCC.
3 A2 input Address input bit 2 (MSB). Binary-weighted select input; combined with A0 and A1 selects one of eight outputs Y0-Y7. CMOS input, VIH ≥ 0.7·VCC, VIL ≤ 0.2·VCC.
4 E1 input Enable input 1, active LOW. All outputs Y0-Y7 are LOW unless E1 = LOW, E2 = LOW, and E3 = HIGH.
5 E2 input Enable input 2, active LOW. All outputs Y0-Y7 are LOW unless E1 = LOW, E2 = LOW, and E3 = HIGH.
6 E3 input Enable input 3, active HIGH. All outputs Y0-Y7 are LOW unless E1 = LOW, E2 = LOW, and E3 = HIGH.
7 Y7 output Decoded output 7 (A2=1, A1=1, A0=1). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V.
8 GND power_in Ground reference (0 V). Connect to system ground.
9 Y6 output Decoded output 6 (A2=1, A1=1, A0=0). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V.
10 Y5 output Decoded output 5 (A2=1, A1=0, A0=1). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V.
11 Y4 output Decoded output 4 (A2=1, A1=0, A0=0). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V.
12 Y3 output Decoded output 3 (A2=0, A1=1, A0=1). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V.
13 Y2 output Decoded output 2 (A2=0, A1=1, A0=0). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V.
14 Y1 output Decoded output 1 (A2=0, A1=0, A0=1). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V.
15 Y0 output Decoded output 0 (A2=0, A1=0, A0=0). Active-HIGH when enabled; otherwise LOW. Push-pull CMOS output, IOL/IOH = ±7.8 mA at VCC = 6 V.
16 VCC power_in Positive supply voltage, 2 V to 6 V (recommended). Decouple with 0.1 µF ceramic capacitor to GND placed close to the pin.
