Quad Bus Buffer

The TC74VHCT125A/126A are high speed CMOS QUAD BUS

They achieve the high speed operation similar to equivalent

Bipolar Shottky TTL while maintaining the CMOS low power

dissipation.

The TC74VHCT125A requires the 3-state control input G to

be set high to place the output into the high impedance state,

whereas the TC74VHCT126A requires the control input G to be

set low to place the output into high impedance.

The input voltage are compatible with TTL output voltage.

This device may be used as a level converter for interfacing

3.3 V to 5 V system.

Input protection and output circuit ensure that 0 to 5.5 V can

the supply voltage. There structure prevents device detsruction

due to mismatched supply and input/output voltages such as

battery back up, hot board insertion, etc.

Note:

Features

• Power down protection is provided on all inputs and outputs.

• Pin and function compatible with the 74 series

(74AC/HC/F/ALS/LS etc.) 125/126 types.
