74LVC1G126DBVRG4

Texas Instruments · Buffer/Driver/Transceiver · SOT-23-5

74LVC1G126DBVRG4 from Texas Instruments, 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 Output enable input: when OE is low the Y output is disabled (high impedance), and when OE is high the A input flows to Y. Tie OE to GND to hold Y in high impedance during power-up and power-down.
2 A input Data input, specified for 0 V to 5.5 V regardless of VCC; unused inputs must be tied to VCC or GND and must not be left floating.
3 GND power_in Ground pin; the continuous current through GND is limited to ±100 mA together with VCC.
4 Y tri_state Three-state push-pull output rated at -24 mA IOH and 24 mA IOL at VCC = 3 V, with continuous output current limited to ±50 mA; do not tie it directly to VCC or GND, and unused outputs may be left open.
5 VCC power_in Supply pin with a recommended operating range of 1.65 V to 5.5 V and an absolute maximum of 6.5 V; a 0.1 µF bypass capacitor to GND is recommended.
