Each of the two elements has independent set (preset) and reset inputs, plus complementary Q and Q̅ outputs. The 5.8 ns propagation delay at 5 V and 50 pF load sets the timing margin for high-speed data paths and state machines running on a 5 V rail. Supply range is 4.5 V to 5.5 V, and quiescent current sits at 16 mA. Outputs source 1 mA and sink 20 mA — enough to drive a couple of standard TTL loads or feed a bus transceiver. ## 145 MHz clock and 5.8 ns propagation delay — timing budget for fast logic The 145 MHz clock rating and 5.8 ns propagation delay (max at 5 V, 50 pF) define the timing window for high-speed logic paths. ## Lifecycle and supply posture The SN74F74D carries an Active lifecycle status with ROHS3 compliance. For a BOM line that needs a proven 5 V flip-flop in a rework-friendly SOIC package, this part is a straightforward fit.","metaTitle":"SN74F74D D-Type Flip-Flop, 145 MHz, 14-SOIC - TI 74F","metaDescription":"TI SN74F74D dual D-type flip-flop with set/reset, 145 MHz clock, 5.8 ns propagation delay, complementary outputs. 14-SOIC, 4.5-5.5 V supply.
