with LSTTL–Compatible Inputs

The MC74VHC1GT126 is a single gate noninverting 3–state buffer
fabricated with silicon gate CMOS technology. It achieves high speed
operation similar to equivalent Bipolar Schottky TTL while
maintaining CMOS low power dissipation.
MARKING DIAGRAM
The MC74VHC1GT126 requires the 3–state control input (OE) to
be set Low to place the output into the high impedance state.
The device input is compatible with TTL–type input thresholds and
the output has a full 5V CMOS level output swing. The input
protection circuitry on this device allows overvoltage tolerance on the
input, allowing the device to be used as a logic–level translator from
3.0V CMOS logic to 5.0V CMOS Logic or from 1.8V CMOS logic to
3.0V CMOS Logic while operating at the high–voltage power supply.
The MC74VHC1GT126 input structure provides protection when
voltages up to 7V are applied, regardless of the supply voltage. This
allows the MC74VHC1GT126 to be used to interface 5V circuits to
