Additional Details

The TC74LCX244FK-ELK features TTL-compatible inputs, allowing seamless integration with 5V TTL logic while operating at a lower 3.3V. The 3-state outputs facilitate bus interface applications, allowing multiple devices to share the same bus lines. This device provides a high output drive capability (±24 mA), ensuring reliable signal transmission even with high capacitive loads. The low power consumption (ICC = 10 μA max) makes it suitable for portable applications. The FK indicates that the device comes in a VSSOP (Very Small Shrink Outline Package) and the ELK likely specifies a particular packaging and reel option. This device is an excellent choice for buffering signals and driving buses in high-speed, low-voltage digital systems.
