INTEGRATED CIRCUITS 74F74 Dual D-type flip-flop Product specification Supercedes data of 1990 Oct 23 IC15 Data Handbook 1996 Mar 12 Philips Semiconductors Philips Semiconductors Product specification Dual D-type flip-flop 74F74 FEATURE Industrial temperature range available (–40°C to +85°C) DESCRIPTION The 74F74 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.
