74HCT27D.652 Nexperia

The Nexperia 74HCT27D652 is a high-performance CMOS logic gate series equipped with five independent 2-input NAND gates with Schmitt-trigger input. The gate inputs are optimized for lower input threshold levels and better noise immunity, providing inputs that remain stable when rapidly fluctuating signals are applied. This feature makes the 74HCT27D652 ideal for active-low computer interface applications since it allows the system to respond to active-low signals without the need for additional noise immunity components. The output features balanced drive for improved noise immunity, with individual series resistors for each output providing a push-pull active sink capability to drive up to 10 mA total load. It operates over a wide supply range of 2V to 5.5V, and the output is fully compatible with TTL levels making the 74HCT27D652 suitable for interfacing between standard TTL and CMOS circuits.
