Additional Details

The TC74LCX16373AFT 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. The transparent latch operation means that the output follows the input when the latch enable (LE) is high, and the output is latched when LE goes low. This device provides a high output drive capability (±24 mA), ensuring reliable signal transmission across the bus. The low power consumption (ICC = 10 μA max) makes it suitable for portable applications. The AFT suffix indicates that the part is supplied in tape and reel packaging, suitable for automated assembly processes. It is available in surface-mount packages for efficient board assembly.
