SN74HCS137PWR

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

SN74HCS137PWR 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 0 input, latched by LE when LE is high and used to select one of the eight outputs.
2 A1 input Address select 1 input, latched by LE when LE is high and used to select one of the eight outputs.
3 A2 input Address select 2 input, latched by LE when LE is high and used to select one of the eight outputs.
4 LE input Active-low latch enable; when low the device acts as a standard three-to-eight decoder, and when high the address latch retains its previous state.
5 G1 input Active-low strobe input 1; when it disables the outputs, all outputs are forced into the high state.
6 G0 input Strobe input 0; when the outputs are gated by this strobe, all outputs are forced into the high state.
7 Y7 output Decoder output 7; low only when it is the selected output and the outputs are not disabled by the strobes, otherwise high.
8 GND power_in Ground reference for the device.
9 Y6 output Decoder output 6; low only when it is the selected output and the outputs are not disabled by the strobes, otherwise high.
10 Y5 output Decoder output 5; low only when it is the selected output and the outputs are not disabled by the strobes, otherwise high.
11 Y4 output Decoder output 4; low only when it is the selected output and the outputs are not disabled by the strobes, otherwise high.
12 Y3 output Decoder output 3; low only when it is the selected output and the outputs are not disabled by the strobes, otherwise high.
13 Y2 output Decoder output 2; low only when it is the selected output and the outputs are not disabled by the strobes, otherwise high.
14 Y1 output Decoder output 1; low only when it is the selected output and the outputs are not disabled by the strobes, otherwise high.
15 Y0 output Decoder output 0; low only when it is the selected output and the outputs are not disabled by the strobes, otherwise high.
16 VCC power_in Positive supply; recommended operating range is 2 V to 6 V (nominal 5 V) per the recommended operating conditions.
