U74LVC1G07G-AL5-R

UTC Unisonic Tech · Buffers, Drivers, Receivers, Transceivers · SOT-353

U74LVC1G07G-AL5-R from UTC Unisonic Tech, in a SOT-353. 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 NC unconnected No connect pin, not internally connected to the function.
2 A input Buffer input; accepts voltages 0 to 5.5V, with output Y high-Z (open-drain) when A is high and low when A is low.
3 GND power_in Ground pin, 0V reference.
4 Y output Open-drain output that pulls low when A is low and is high-impedance when A is high, accepts voltage up to 5.5V and sinks ±24mA at VCC=3.3V.
5 VCC power_in Supply voltage pin, 1.65V to 5.5V operating range (absolute maximum 6.5V).
