CD74ACT04M

CD74ACT04M Description

The CD74ACT04M from Harris Corporation is a hex inverter integrated circuit (IC) belonging to the 74ACT series, designed for high-speed logic applications. Housed in a 14-pin SOIC package, this surface-mount device features six independent inverters, each with a single input. Operating within a 4.5V to 5.5V supply range, it delivers TTL-compatible input thresholds (0.8V Low, 2V High) and robust 24mA output drive capability, making it suitable for interfacing with both CMOS and TTL logic families. With a maximum propagation delay of 9.3ns at 5V and 50pF load, it ensures high-speed signal processing while maintaining low power consumption (4µA quiescent current).

CD74ACT04M Features

• High-Speed Performance: 9.3ns propagation delay at 5V ensures rapid signal inversion for time-critical applications.
• Wide Voltage Range: Operates from 4.5V to 5.5V, compatible with standard 5V systems.
