The HCT variant (SN74HCT74DT) accepts TTL-level input voltages directly, while the HC variant (SN74HC74D) expects CMOS-level inputs. If your upstream logic is 5 V TTL (e.g., 74LS or 74ALS), the HCT version avoids a level-shifter."},{"question":"What is the SN74HCT74DT's clock frequency and propagation delay?","answer":"Maximum clock frequency is 46 MHz. Maximum propagation delay is 25 ns at 5.5 V supply into a 50 pF load.
