SN74AUC1G19DBVR

Texas Instruments · Signal Switches, Multiplexers, Decoders · SOT-23-6

SN74AUC1G19DBVR from Texas Instruments, in a SOT-23-6. 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 A input Data input A, buffered and passed to Y0 (true) and Y1 (complement) when enable E is low.
2 GND power_in Ground reference pin for the device.
3 E input Active-low enable input; when E is low, A is decoded to the outputs, and when E is high, Y0 is high and Y1 is high.
4 Y1 output Complemented output Y1, which is high when A is low and E is low.
5 VCC power_in Positive supply pin; the datasheet specifies 0.8 V to 2.7 V VCC operation, designed specifically for 1.65 V to 1.95 V.
6 Y0 output True output Y0, which is high when A is high and E is low.
