Texas Instruments · Global Sourcing Parts · SOIC-16

CD74HCT138M96 from Texas Instruments, in a SOIC-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 input 0; selects one of eight outputs in conjunction with A1 and A2.
2 A1 input Address input 1; selects one of eight outputs in conjunction with A0 and A2.
3 A2 input Address input 2; selects one of eight outputs in conjunction with A0 and A1.
4 G0 input Active-low output strobe 0; combined with G1 and G2 for output enable control.
5 G1 input Active-low output strobe 1; combined with G0 and G2 for output enable control.
6 G2 input Output strobe 2; combined with G0 and G1 for output enable and decoder cascading.
