74HC238D from Nexperia, 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 (LSB). CMOS input; contributes to selecting one of eight outputs.
2	A1	input	Address input bit 1. CMOS input; contributes to selecting one of eight outputs.
3	A2	input	Address input bit 2 (MSB). CMOS input; contributes to selecting one of eight outputs.
4	E1	input	Enable input 1, active LOW. Both E1 and E2 must be LOW (and E3 HIGH) for a selected output to go HIGH; otherwise all outputs are LOW.
5	E2	input	Enable input 2, active LOW. Both E1 and E2 must be LOW (and E3 HIGH) for a selected output to go HIGH.
6	E3	input	Enable input 3, active HIGH. Must be HIGH (with E1 and E2 LOW) to enable outputs; can be used as the data input in demultiplexer mode.
7	Y7	output	Decoded output 7 (active HIGH). Selected when A2:A0 = 111 and the chip is enabled; otherwise LOW.
8	GND	power_in	Ground reference (0 V).
9	Y6	output	Decoded output 6 (active HIGH). Selected when A2:A0 = 110 and the chip is enabled; otherwise LOW.
10	Y5	output	Decoded output 5 (active HIGH). Selected when A2:A0 = 101 and the chip is enabled; otherwise LOW.
11	Y4	output	Decoded output 4 (active HIGH). Selected when A2:A0 = 100 and the chip is enabled; otherwise LOW.
12	Y3	output	Decoded output 3 (active HIGH). Selected when A2:A0 = 011 and the chip is enabled; otherwise LOW.
13	Y2	output	Decoded output 2 (active HIGH). Selected when A2:A0 = 010 and the chip is enabled; otherwise LOW.
14	Y1	output	Decoded output 1 (active HIGH). Selected when A2:A0 = 001 and the chip is enabled; otherwise LOW.
15	Y0	output	Decoded output 0 (active HIGH). Selected when A2:A0 = 000 and the chip is enabled; otherwise LOW.
16	VCC	power_in	Supply voltage. Operating range 2.0 V to 6.0 V (74HC238); 4.5 V to 5.5 V (74HCT238).
