Product Summary

The NTE74HC240 (inverting) and NTE74HC244 (non−inverting) are 3−state buffers in a 20−Lead DIP-type package that utilize advanced silicon−gate CMOS technology to achieve the high-noise immunity and low-power consumption of standard CMOS integrated circuits. Both devices have active−low output enables. Features:
Typical propagation delay: 8ns
Wide power supply range: 2V to 6V
High-noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
3−State outputs
Buffered inputs
High−current bus driver outputs
Fanout (over temperature range):
Standard outputs 10 LS−TTL loads
Bus driver outputs 15 LS−TTL loads
Balanced propagation delay and transition times
Significant power reduction compared to LS−TTL logic ICs
