Octal Bus Buffer

TC74VHCT240AF/AFT/AFK

Inverted, 3-State Outputs

TC74VHCT244AF/AFT/AFK

Non-Inverted, 3-State Outputs

TC74VHCT240AF, TC74VHCT244AF

The TC74VHCT240A and 244A 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 TC74VHCT240A is an inverting 3-state buffer having two

active-low output enables. The TC74VHCT244A 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.

The input voltage are compatible with TTL output voltage.

These devices may be used as a level converter for interfacing

3.3 V to 5 V system.

Weight

Input protection and output circuit ensure that 0 to 5.5 V can

be applied to the input and output ^(Note)pins without regard to

the supply voltage. These structure prevents device destruction

due to mismatched supply and input/output voltages such as

battery back up, hot board insertion, etc.

Note:

Output in off-state
