NLSF3T126
Quad Bus Buffer
with 3−State Control Inputs
The NLSF3T126 is a high speed
CMOS quad bus buffer fabricated with silicon gate
CMOS technology. It achieves noninverting high speed operation similar to equivalent Bipolar Schottky TTL while maintaining
CMOS low power dissipation.
The NLSF3T126 requires the 3−state control input (OE) to be set Low to place the output into high impedance.
The T126 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 NLSF3T126 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 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.
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.
