2-Input AND Gate / CMOS Logic Level Shifter - ON Semiconductor
Description
NL17SHT08
2-Input AND Gate / CMOS Logic Level Shifter
The NL17SHT08 is an advanced high speed CMOS 2−input AND 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 NL17SHT08 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage.
This allows the NL17SHT08 to be used to interface 5 V circuits to 3 V circuits.
The output structures also provide protection when VCC = 0 V.
These input and output structures help prevent device destruction caused by supply voltage − input/output voltage mismatch, battery backup, hot insertion, etc.
