NC7SZ126M5X

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

NC7SZ126M5X from onsemi, 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 HIGH the output follows A, when LOW the output Y is in the high-impedance state; unused inputs must be held HIGH or LOW and may not float, and inputs tolerate up to 6V.
2 A input Buffer data input; inputs tolerate voltages up to 6V independent of VCC and must not be left floating.
3 GND power_in Ground pin.
4 Y output 3-STATE buffer output with ±24 mA drive at 3V VCC; goes high impedance when OE is LOW and tolerates voltages above VCC in the 3-STATE condition (0V to 5.5V).
5 VCC power_in Positive supply pin; operating range 1.65V to 5.5V (absolute maximum -0.5V to +6V).
