NL17SHT00
Single 2-Input NAND Gate/
CMOS Logic Level Shifter
LSTTL−Compatible Inputs
The NL17SHT00 is a single gate 2−input NAND fabricated with
silicon gate CMOS technology.
The internal circuit is composed of multiple 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 NL17SHT00 input structure provides protection when voltages
up to 7 V are applied, regardless of the supply voltage. This allows the
NL17SHT00 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.
