It operates from a 4.5 V to 5.5 V supply and is specified over the industrial temperature range of -40°C to 85°C. The device is packaged in a through-hole DIP, making it suitable for legacy bus-interface designs, address latching, and general-purpose register storage in industrial control, telecom, and test equipment. ## 30 MHz clock and 46 ns propagation delay — timing budget fit The 30 MHz maximum clock frequency and 46 ns propagation delay (at 5 V supply, 150 pF load) define the timing margin for bus-oriented designs. ## Active lifecycle — no LTB pressure Note that this variant is RoHS non-compliant (lead-bearing), which may affect its eligibility for new designs under certain environmental compliance programs. ## Quiescent current and output drive Quiescent current is 8 µA typical, keeping the static power draw negligible in battery-backed or low-standby systems. Each output can source or sink 7.2 mA, adequate for driving TTL loads, LED indicators, or the inputs of a following logic stage. The input capacitance is 10 pF per input, a standard load for 5 V CMOS and TTL drivers.","metaTitle":"MM74HCT374J D-Type Flip-Flop, 30 MHz, 46 ns, 74HCT, DIP","metaDescription":"Fairchild 74HCT374J D-Type flip-flop: 8-bit, positive-edge triggered, tri-state output, 30 MHz clock, 46 ns prop delay, -40 to 85°C.
