The MM74HCT244MTC is a dual-channel non-inverting buffer from Fairchild Semiconductor, part of the 74HCT logic family. It operates from a 4.5V to 5.5V supply and features 3-State outputs for bus-oriented applications. Each output can source or sink 7.2mA, making it suitable for driving moderate loads. The 20-TSSOP package is compact for space-constrained PCBs. Typical applications include bus interfacing, signal buffering, and level translation in 5V digital systems.
- TTL-Compatible Inputs: Directly interfaces with 5V TTL logic without extra components.
- 3-State Outputs: Enables bus sharing and prevents data contention in multiplexed systems.
- Wide Temperature Range: -40°C to 85°C ensures reliable operation in industrial environments.
- Compact TSSOP Package: Saves board space while providing adequate thermal performance.
