INTEGRATED CIRCUITS 74LVT74 3.3V Dual D-type flip-flop Product specification IC24 Data Handbook       1996 Aug 28 Philips Semiconductors Product specification 3.3V Dual D-type flip-flop 74LVT74 QUICK REFERENCE DATA SYMBOL DESCRIPTION CONDITIONS Tamb = 25°C; GND = 0V PARAMETER tPLH tPHL Propagation delay CPn to Qn CL = 50pF; VCC = 3.3V CIN Input capacitance VI = 0V or 3.0V ICC Total supply current VCC = 3.6V TYPICAL UNIT 3.1 3.6 ns 3 pF 0.5 mA The 74LVT74 is a dual positive edge-triggered D-type flip-flop featuring individual data, clock, set, and reset inputs; also true and complementary outputs. Set (SD) and reset (RD) are asynchronous active low inputs and operate independently of the clock input. When set and reset are inactive (high), data at the D input is transferred to the Q and Q outputs on the low-to-high transition of the clock. Data must be stable just one setup time prior to the low-to-high transition of the clock for predictable operation. Clock triggering occurs at a voltage level and is not directly related to the transition time of the positive-going pulse. Following the hold time interval, data at the D input may be changed without affecting the levels of the output.

Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
