M74VHC1GT126DF2G

onsemi · Buffers, Drivers, Receivers, Transceivers · SOT-353

M74VHC1GT126DF2G from onsemi, in a SOT-353. 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 high the output Y is placed in the high-impedance (Z) state, and when OE is low Y follows A per the function table.
2 A input Data input of the noninverting buffer, with input structures that tolerate up to 5.5 V regardless of VCC; this MC74VHC1GT126 variant has TTL-level thresholds (VIH minimum 2.0 V and VIL maximum 0.8 V at VCC of 4.5 V to 5.5 V).
3 GND power_in Ground reference pin for the device.
4 Y tri_state Buffered 3-state output rated for 8 mA source/sink at 3.0 V and an absolute maximum output current of ±25 mA.
5 VCC power_in Positive supply pin; recommended operating range is 2.0 V to 5.5 V, with an absolute maximum DC supply voltage of 6.5 V for this package.
