Outputs

TC74HCT244AP/AF

Non-Inverted,

3-State Outputs

The TC74HCT240A, and HCT244A are high speed CMOS

technology.

They achieve the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

Their inputs are compatible with TTL, NMOS, and CMOS

output voltage levels. The TC74HCT240A is an inverting 3-state

buffer having two active-low output enables. The TC74HCT244A

is non-inverting 3-state buffer the HCT244A has two active-low

output enables.

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

address drivers, etc.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features
