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