NLSF3T125
Quad Bus Buffer
with 3-State Control Inputs
The NLSF3T125 is a high speed CMOS quad bus 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 NLSF3T125 requires the 3-state control input (OE) to be set
High to place the output into the high impedance state.
The T125 inputs are compatible with TTL levels. This device can be
used as a level converter for interfacing 3.3 V to 5.0 V, because it has
full 5.0 V CMOS level output swings.
The NLSF3T125 input structures provide protection when voltages
between 0 V and 5.5 V are applied, regardless of the supply voltage.
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.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V
systems to 3.0 V systems.
