The TC74VHCT240A and 244A are advanced high speed
CMOS OCTAL BUS BUFFERs fabricated with silicon gate

MOS 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.
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.
