Non-Inverted, 3-State Outputs

The TC74VHC240 and 244 are advanced high speed CMOS

OCTAL BUS BUFFERs fabricated with silicon gate C²MOS

technology.

They achieve the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

The 74VHC240 is an inverting 3-state buffer having two

active-low output enables. The TC74VHC244 is a non-inverting

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

These devices are designed to be used with 3-state memory

address drivers, etc.

An input protection circuit ensures that 0 to 5.5 V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.
