Wuxi I core Elec · Signal Switches, Multiplexers, Decoders · SOP-16

AiP74HC138SA16.TR from Wuxi I core Elec, in a SOP-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 (binary weight 1, LSB) that selects which one of the eight active-low outputs Y0 to Y7 goes low; input clamp diodes allow voltages above VCC through a current-limiting resistor.
2 A1 input Address input (binary weight 2) that selects which one of the eight active-low outputs goes low; input clamp diodes allow voltages above VCC through a current-limiting resistor.
3 A2 input Address input (binary weight 4, MSB) that selects which one of the eight active-low outputs goes low; input clamp diodes allow voltages above VCC through a current-limiting resistor.
4 E1 input Active-low enable input; all outputs stay high unless E1 and E2 are low and E3 is high.
5 E2 input Active-low enable input; all outputs stay high unless E1 and E2 are low and E3 is high.
6 E3 input Active-high enable input; all outputs stay high unless E1 and E2 are low and E3 is high.
7 Y7 output Active-low mutually exclusive decoder output, low when address A2A1A0 = 111 and the device is enabled.
8 GND power_in Ground reference (0 V) for the device.
9 Y6 output Active-low mutually exclusive decoder output, low when address A2A1A0 = 110 and the device is enabled.
10 Y5 output Active-low mutually exclusive decoder output, low when address A2A1A0 = 101 and the device is enabled.
11 Y4 output Active-low mutually exclusive decoder output, low when address A2A1A0 = 100 and the device is enabled.
12 Y3 output Active-low mutually exclusive decoder output, low when address A2A1A0 = 011 and the device is enabled.
13 Y2 output Active-low mutually exclusive decoder output, low when address A2A1A0 = 010 and the device is enabled.
14 Y1 output Active-low mutually exclusive decoder output, low when address A2A1A0 = 001 and the device is enabled.
15 Y0 output Active-low mutually exclusive decoder output, low when address A2A1A0 = 000 and the device is enabled.
16 VCC power_in Supply voltage; the datasheet's recommended range for the AiP74HC138 (CMOS-level part) is 2.0 V to 6.0 V.
