Non-Inverted, 3-State

Outputs

The TC74AC240 and 244 are advanced high speed CMOS

OCTAL BUS BUFFERs fabricated with silicon gate and

They achieve the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

The 74AC240 is an inverting 3-state buffer while the 74AC244

is non-inverting. Both devices have two active-low output

enables.

These devices are designed to be used in such applications as

3-state memory address drivers.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.
