Non-Inverted, 3-State

Outputs

The TC74AC240 and 244 are advanced high speed CMOS

OCTAL BUS BUFFERs fabricated with silicon gate and

double-layer metal wiring C²MOS technology.

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.
