The 74HCT74DB from NXP Semiconductors is a dual positive edge-triggered D-type flip-flop. Each flip-flop has individual data (D), clock (CP), set (SD), and reset (RD) inputs, along with complementary Q and Q outputs. Data meeting setup and hold time requirements on the low-to-high clock transition is stored and appears at the Q output.
This device operates with TTL level inputs and features a clock frequency of up to 54 MHz. The supply voltage range is from 4.5V to 5.5V. It offers symmetrical output impedance, low power dissipation, and high noise immunity. The flip-flop is specified from -40°C to +125°C and comes in a 14-SSOP package suitable for surface mounting.
Key electrical characteristics include a maximum propagation delay of 53ns at 4.5V and 50pF, and output currents of 4mA high and low. The Schmitt-trigger action on the clock input provides tolerance for slower clock rise and fall times. Clamp diodes on the inputs allow for current-limiting resistors to interface with voltages exceeding VCC.
