74AC11138DR

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

74AC11138DR 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	Y1	output	Data output Y1 of the 3-to-8 decoder, active when selected by the A, B, C inputs and the enable inputs.
2	Y2	output	Data output Y2 of the 3-to-8 decoder, active when selected by the A, B, C inputs and the enable inputs.
3	Y3	output	Data output Y3 of the 3-to-8 decoder, active when selected by the A, B, C inputs and the enable inputs.
4	GND	power_in	Ground reference pin for the device.
5	Y4	output	Data output Y4 of the 3-to-8 decoder, active when selected by the A, B, C inputs and the enable inputs.
6	Y5	output	Data output Y5 of the 3-to-8 decoder, active when selected by the A, B, C inputs and the enable inputs.
7	Y6	output	Data output Y6 of the 3-to-8 decoder, active when selected by the A, B, C inputs and the enable inputs.
8	Y7	output	Data output Y7 of the 3-to-8 decoder, active when selected by the A, B, C inputs and the enable inputs.
9	G2B	input	Active-low input enable G2B; must be low together with G2A and G1 high to enable the outputs.
10	G2A	input	Active-low input enable G2A; must be low together with G2B and G1 high to enable the outputs.
11	G1	input	Active-high input enable G1; must be high, with G2A and G2B low, to enable the outputs.
12	VCC	power_in	Supply pin; recommended supply range is 3 V to 5.5 V and the absolute maximum is 7 V (limits from Section 4 on page 4).
13	C	input	Binary select input C, the most significant select bit of the 3-to-8 decode.
14	B	input	Binary select input B, the middle select bit of the 3-to-8 decode.
15	A	input	Binary select input A, the least significant select bit of the 3-to-8 decode.
16	Y0	output	Data output Y0 of the 3-to-8 decoder, active when selected by the A, B, C inputs and the enable inputs.
