NL17SHT126
Noninverting Buffer /
CMOS Logic Level Shifter
with LSTTL−Compatible Inputs
The NL17SHT126 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.
The NL17SHT126 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 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 NL17SHT126 input structure provides protection when
voltages up to 7 V are applied, regardless of the supply voltage. This
allows the NL17SHT126 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.
