NL17SHT32
2-Input OR Gate /
CMOS Logic Level Shifter
The NL17SHT32 is an advanced high speed CMOS 2−input OR
gate fabricated with silicon gate CMOS technology. It achieves high
speed operation similar to equivalent Bipolar Schottky TTL while
maintaining CMOS low power dissipation.

The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output.
The device input is compatible with TTL−type input thresholds and
the output has a full 5 V 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 V
CMOS logic to 5 V CMOS Logic or from 1.8 V CMOS logic to 3 V
CMOS Logic while operating at the high−voltage power supply.
The NL17SHT32 input structure provides protection when voltages
up to 7 V are applied, regardless of the supply voltage. This allows the
NL17SHT32 to be used to interface 5 V circuits to 3 V circuits. The
