The TC74VHCV240 and 244 are advanced high speed CMOS

OCTAL BUS BUFFERs fabricated with silicon gate CMOS

technology.

They achieve the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

The 74VHCV240 is an inverting 3-state buffer having two

active-low output enables. The TC74VHCV244 is a non-inverting

3-state buffer, and has two active-low output enables.

Input pin have hysteresis between the positive-going and

negative-going thresholds. Thus the TC74VHCV240 and 244 are

capable of squaring up transitions of slowly changing input

signals and provides an improved noise immunity.

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

applied to the input and output ^(Note)pins without regard to the

supply voltage. These structure prevents device destruction due

to mismatched supply and input/output voltages such as battery

back up, etc.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or

even destruction.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the

significant change in temperature, etc.) may cause this product to decrease in the reliability significantly

even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute

maximum ratings and the operating ranges.

Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook

(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test

report and estimated failure rate, etc).
