Description

The 74HC74N is a dual D-type Flip-Flop with set and reset and positive-edge trigger. This has individual data (nD), clock (nCP), set (nSD) and reset (nRD) inputs and complementary nQ and nQ outputs. Data at the nD-input that meets the set-up and hold time requirements on the low-to-high clock transition and is stored in the flip-flop and appears at the nQ output. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Symmetrical output impedance
Low power dissipation
High noise immunity
Balanced propagation delays
ESD protection HBM JESD22-A114F exceeds 2000V
ESD sensitive device, take proper precaution while handling the device.
