SN74LVC1G126DB

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

SN74LVC1G126DB 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 Output enable input: when OE is low the Y output is forced to high impedance (Z), and when high the output follows A; the datasheet gives VIH/VIL limits per VCC (for example VIH 0.7×VCC at 4.5 V to 5.5 V and VIL 0.3×VCC at 4.5 V to 5.5 V).
2 A input Data input that is buffered to output Y and accepts 3.3 V or 5 V logic levels, with input voltage rated 0 V to 5.5 V.
3 GND power_in Ground reference, 0 V.
4 Y tri_state Three-state buffered data output that follows A when OE is high and is high impedance when OE is low, with ±24 mA drive at VCC = 3.0 V and output voltage limited to 0 V to VCC in operating mode.
5 VCC power_in Supply voltage, 1.65 V to 5.5 V recommended operating range with absolute maximum of -0.5 V to +6.5 V.
