SN74LV1T125DB

lingxingic · Buffers, Drivers, Receivers, Transceivers · SOT-23-5

SN74LV1T125DB from lingxingic, in a SOT-23-5. 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 OE input Active-high output enable: when OE is high the Y output goes to high impedance (Z), and when OE is low the buffer drives Y from A; recommended VCC range is 1.6 V to 5.5 V.
2 A input Data input, 5 V tolerant, with a recommended input voltage range of 0 V to 5.5 V, which allows level-down translation from a higher supply.
3 GND power_in Ground reference (0 V).
4 Y output Three-state data output that swings between GND and VCC; in the high-impedance (OE high) or power-off state it is rated for at most 4.6 V.
5 VCC power_in Supply voltage: recommended operating range 1.6 V to 5.5 V (typical 5.0 V), absolute maximum 7.0 V.
