Performance and Quality

The CD74ACT373M features a high drive output (-24mA IOL, 24mA IOH) which is crucial for high-speed driving of bus lines in a system without need for interface or pull-up components. It has a low input current of 1µA max, and a typical tpd of 8ns. It is designed to interface directly with 5V TTL systems. The robustness of the device is further underscored by its latch-up performance which exceeds 250mA on 7V to 7V under maximum operating conditions.

Applications

This versatile latch is widely used across various applications including:

• Buffer memory
• Bus drivers
• Data storage
• Control systems
• Communication systems
