It captures data on the positive edge of the clock and presents it on tri-state, non-inverted outputs — meaning the outputs can be driven high, low, or placed in a high-impedance state for bus sharing. The 100 MHz clock frequency and 17 ns propagation delay (at 5 V, 15 pF) make it a fit for moderate-speed address/data latching in 5 V TTL systems. It is a through-hole part in a 20-pin DIP (0.300\" body), so it goes into socketed boards or prototype builds, not a reflow line. ## Supply and temperature — the operating envelope The part runs on a 4.75 V to 5.25 V supply. The 0°C to 70°C commercial temperature grade means it is specified for indoor, climate-controlled equipment. ## Output drive and quiescent current Each output can source 6.5 mA (IOH) — enough to drive one or two standard TTL loads or a low-power LED indicator, but not a heavy bus without a buffer. The quiescent supply current (Iq) sits at 110 mA, which is typical for a Schottky 8-bit register and means the part draws that current even when idle. For battery-powered or thermally constrained boards, the 74LS or 74HC families draw significantly less standby current. ## Lifecycle and sourcing The SN74S374N carries an Active product status. It is sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"SN74S374N D-Type Flip-Flop, 8-Bit, 100 MHz, 20-DIP","metaDescription":"SN74S374N D-Type flip-flop, 8-bit, positive-edge triggered, tri-state outputs. 100 MHz clock, 17 ns propagation delay.

It runs at a lower 40 MHz clock frequency versus 100 MHz for the SN74S374N, has a longer 27 ns propagation delay (at 5 V, 15 pF), and draws significantly less quiescent current (22 mA typical vs 110 mA). Both are 8-bit D-type flip-flops with tri-state outputs in the same 20-pin DIP footprint, so they are pin-compatible. The choice depends on whether you need the speed of the 74S or the lower power of the 74LS."},{"question":"What is the SN74S374N used for?","answer":"It is an 8-bit D-type register used for data latching, address buffering, and bus interfacing in 5 V TTL logic systems.
