74LVC1G126CT05ARCQ

GR · Buffers, Drivers, Receivers, Transceivers · SC-70-5

74LVC1G126CT05ARCQ from GR, in a SC-70-5. 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 output Y is disabled (high impedance), and when OE is high the output follows A.
2 A input Data input of the buffer; the datasheet states inputs accept voltages up to 5.5 V.
3 GND power_in Ground reference, 0 V, to which all voltages are referenced.
4 Y output 3-state buffer output with ±24 mA drive at 3.3 V VCC, high impedance when OE is low.
5 VCC power_in Supply voltage for 1.65 V to 3.6 V operation; the datasheet also states 5 V VCC operation is supported.
