Nexperia 74HCT74D Dual D-Type Flip-Flop SOIC14, 15ns, 59MHz

The Nexperia 74HCT74D is a dual positive edge-triggered D-type flip-flop with individual data (nD), clock (nCP), set (nSD) and reset (nRD) inputs, along with complementary outputs (nQ and nQ). This IC is designed to store data at the nD input on the low-to-high clock transition, provided that set-up and hold time requirements are met.

A Schmitt-trigger action on the clock input ensures high tolerance to slower clock rise and fall times, enhancing reliability in various operating conditions. The device includes clamp diodes, allowing the use of current limiting resistors to interface inputs to voltages above VCC, offering design flexibility. With symmetrical output impedance, low power dissipation, high noise immunity, and balanced propagation delays, this flip-flop delivers stable performance. It complies with JEDEC standard No. 7A and features TTL input levels for seamless integration.
