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

CD74HC137PWR 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 A0, the least significant bit of the 3-bit decoder address
2 A1 input Address select input A1, the middle bit of the 3-bit decoder address
3 A2 input Address select input A2, the most significant bit of the 3-bit decoder address
4 LE input Latch Enable input, active high; when high, latches the A0-A2 address inputs
5 OE1 input Output Enable input 1; selected output is active when OE0=H and OE1=L
6 OE0 input Output Enable input 0; selected output is active when OE0=H and OE1=L
7 Y7 output Decoder output 7, active low when selected and enabled
8 GND power_in Ground, 0V reference
9 Y6 output Decoder output 6, active low when selected and enabled
10 Y5 output Decoder output 5, active low when selected and enabled
11 Y4 output Decoder output 4, active low when selected and enabled
12 Y3 output Decoder output 3, active low when selected and enabled
13 Y2 output Decoder output 2, active low when selected and enabled
14 Y1 output Decoder output 1, active low when selected and enabled
15 Y0 output Decoder output 0, active low when selected and enabled
16 VCC power_in Positive supply voltage; 2V to 6V for HC types
