INTEGRATED CIRCUITS 74F74 Dual D-type flip-flop Product specification 1996 Mar 12 Supercedes data of 1990 Oct 23 IC15 Data Handbook Philips Semiconductors Product specification Dual D-type flip-flop 74F74 FEATURE PIN CONFIGURATION Industrial temperature range available (40C to +85C) RD0 1 14 V CC DESCRIPTION D0 2 13 RD1 The 74F74 is a dual positive edge-triggered D-type flip-flop featuring CP0 3 12 D1 individual data, clock, set, and reset inputs also true and SD0 4 11 CP1 complementary outputs. Set (SD) and reset (RD) are asynchronous active low inputs and operate independently of the clock input. When Q0 5 10 SD1 set and reset are inactive (high), data at the D input is transferred to Q0 6 9 Q1 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 GND 7 8 Q1 the clock for predictable operation. Clock triggering occurs at a SF00045 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.
