CD74HCT137M96 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 Binary address select input 0; combined with A1 and A2 selects one of eight outputs; all inputs accept LSTTL-compatible levels (VIH ≥ 2 V, VIL ≤ 0.8 V at VCC = 4.5-5.5 V).
2 A1 input Binary address select input 1; combined with A0 and A2 selects one of eight outputs; can be latched by LE.
3 A2 input Binary address select input 2; combined with A0 and A1 selects one of eight outputs; can be latched by LE.
4 LE input Latch Enable input; active HIGH latches address inputs A0-A2 isolating outputs from subsequent address changes; LOW makes outputs transparent to address inputs.
5 OE1 input Output Enable 1 input (active LOW); HIGH forces all Y outputs inactive (HIGH); must be LOW together with OE0 HIGH to enable decoding.
6 OE0 input Output Enable 0 input (active HIGH); LOW forces all Y outputs inactive (HIGH); must be HIGH together with OE1 LOW to enable decoding.
7 Y7 output Active-LOW decoded output 7; LOW when A2=H, A1=H, A0=H, LE=L, OE0=H, OE1=L; max output sink/source current ±25 mA, VOL ≤ 0.4 V at IOL = 4 mA.
8 GND power_in Ground supply reference, 0 V; maximum DC VCC or ground current ±50 mA.
9 Y6 output Active-LOW decoded output 6; LOW when A2=H, A1=H, A0=L, LE=L, OE0=H, OE1=L; max output sink/source current ±25 mA.
10 Y5 output Active-LOW decoded output 5; LOW when A2=H, A1=L, A0=H, LE=L, OE0=H, OE1=L; max output sink/source current ±25 mA.
11 Y4 output Active-LOW decoded output 4; LOW when A2=H, A1=L, A0=L, LE=L, OE0=H, OE1=L; max output sink/source current ±25 mA.
12 Y3 output Active-LOW decoded output 3; LOW when A2=L, A1=H, A0=H, LE=L, OE0=H, OE1=L; max output sink/source current ±25 mA.
13 Y2 output Active-LOW decoded output 2; LOW when A2=L, A1=H, A0=L, LE=L, OE0=H, OE1=L; max output sink/source current ±25 mA.
14 Y1 output Active-LOW decoded output 1; LOW when A2=L, A1=L, A0=H, LE=L, OE0=H, OE1=L; max output sink/source current ±25 mA.
15 Y0 output Active-LOW decoded output 0; LOW when A2=L, A1=L, A0=L, LE=L, OE0=H, OE1=L; propagation delay tPLH/tPHL ≤ 38 ns at VCC = 4.5 V, CL = 50 pF, 25 °C.
16 VCC power_in Positive supply voltage; 4.5 V to 5.5 V operating range for HCT type; quiescent supply current ICC ≤ 8 µA typical, 80 µA max at 25 °C.
