Texas Instruments · Signal Switches, Multiplexers, Decoders · SOIC-24-300mil

CD74HCT154M96 from Texas Instruments, in a SOIC-24-300mil. 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 Y0 output Active-low decoder output 0, driven low when address A3-A0 = 0000 and both enables are low (standard output, 10 LSTTL loads fanout).
2 Y1 output Active-low decoder output 1, driven low when address A3-A0 = 0001 and both enables are low.
3 Y2 output Active-low decoder output 2, driven low when address A3-A0 = 0010 and both enables are low.
4 Y3 output Active-low decoder output 3, driven low when address A3-A0 = 0011 and both enables are low.
5 Y4 output Active-low decoder output 4, driven low when address A3-A0 = 0100 and both enables are low.
6 Y5 output Active-low decoder output 5, driven low when address A3-A0 = 0101 and both enables are low.
7 Y6 output Active-low decoder output 6, driven low when address A3-A0 = 0110 and both enables are low.
8 Y7 output Active-low decoder output 7, driven low when address A3-A0 = 0111 and both enables are low.
9 Y8 output Active-low decoder output 8, driven low when address A3-A0 = 1000 and both enables are low.
10 Y9 output Active-low decoder output 9, driven low when address A3-A0 = 1001 and both enables are low.
11 Y10 output Active-low decoder output 10, driven low when address A3-A0 = 1010 and both enables are low.
12 GND power_in Ground reference (0 V) for the device.
13 Y11 output Active-low decoder output 11, driven low when address A3-A0 = 1011 and both enables are low.
14 Y12 output Active-low decoder output 12, driven low when address A3-A0 = 1100 and both enables are low.
15 Y13 output Active-low decoder output 13, driven low when address A3-A0 = 1101 and both enables are low.
16 Y14 output Active-low decoder output 14, driven low when address A3-A0 = 1110 and both enables are low.
17 Y15 output Active-low decoder output 15, driven low when address A3-A0 = 1111 and both enables are low.
18 E1 input Enable input 1; a high on either E1 or E2 forces all outputs high, and it can serve as the data input for demultiplexing (1.3 HCT unit loads).
19 E2 input Enable input 2; a high on either E1 or E2 forces all outputs high, and it can serve as the data input for demultiplexing (1.3 HCT unit loads).
20 A3 input Address select input bit 3 (MSB) selecting one of outputs Y0-Y15 (1.4 HCT unit loads).
21 A2 input Address select input bit 2 selecting one of outputs Y0-Y15 (1.4 HCT unit loads).
22 A1 input Address select input bit 1 selecting one of outputs Y0-Y15 (1.4 HCT unit loads).
23 A0 input Address select input bit 0 (LSB) selecting one of outputs Y0-Y15 (1.4 HCT unit loads).
24 VCC power_in Positive supply; HCT types operate from 4.5V to 5.5V (absolute maximum -0.5V to 7V).
