NL17SHT04
Inverting Buffer /
CMOS Logic Level Shifter
LSTTL−Compatible Inputs
The NL17SHT04 is a single gate inverting buffer 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 NL17SHT04 input structure provides protection when voltages
up to 7.0 V are applied, regardless of the supply voltage. This allows
the NL17SHT04 to be used to interface 5 V circuits to 3 V circuits.
The output structures also provide protection when V_CC = 0 V. These
input and output structures help prevent device destruction caused by
supply voltage − input/output voltage mismatch, battery backup, hot
insertion, etc.
