Octal Bus Buffer

TC7MH240FK Inverted, 3-State Outputs

TC7MH244FK Non-Inverted, 3-State Outputs

The TC7MH240FK and TC7MH244FK are advanced high

speed CMOS octal bus buffers fabricated with silicon gate

They achieve the high speed operation similar to equivalent

bipolar schottky TTL while maintaining the CMOS low power

dissipation.

The TC7MH240FK is an inverting 3-state buffer having two

active-low output enables. The TC7MH244FK 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.

Features

• Power down protection is provided on all inputs.

• Pin and function compatible with 74ALS240/244
