It is part of the 74AS (Advanced Schottky) bipolar logic family, which offers a speed-power trade-off between the earlier 74S and the later 74F series. Each of the two flip-flops stores one bit, and the device is supplied in a 14-pin plastic DIP (PDIP-14) for through-hole mounting. Typical applications include register files, shift registers, frequency dividers, and control-latch functions in 5 V digital systems operating in commercial indoor environments (0°C to 70°C ambient). ## 105 MHz clock and 9 ns propagation delay — timing margin for the bus The 105 MHz maximum clock frequency and 9 ns propagation delay at 5 V, 50 pF define the timing envelope. ## Output drive — asymmetric and intentional The SN74AS74AN sources 2 mA and sinks 20 mA per output. ## Supply and temperature — 5 V nominal, indoor only Supply range is 4.5 V to 5.5 V; operating temperature is 0°C to 70°C. ## Lifecycle and sourcing reality The SN74AS74AN is listed as Active on the manufacturer's lifecycle status, with RoHS3 compliance (lead-free). For a BOM line that needs a through-hole DIP flip-flop, this part is a safe choice for new designs and ongoing production.","metaTitle":"SN74AS74AN D-Type Flip-Flop, 105 MHz, 14-PDIP","metaDescription":"TI SN74AS74AN dual D-type flip-flop with set/reset, 105 MHz clock, 9 ns propagation delay, complementary outputs. 4.5-5.5 V supply, 0-70°C.

It clocks at 105 MHz versus roughly 40 MHz for the 74LS equivalent, and its propagation delay is 9 ns versus about 15 ns for the 74LS. The AS version also sinks 20 mA per output versus 8 mA for the LS. Both are dual D-type flip-flops in the same 14-pin DIP footprint, so they are pin-compatible — but the AS part draws higher quiescent current (16 mA vs roughly 4 mA for the LS). Choose the AS when you need the extra speed or drive; choose the LS when power budget is tighter."},{"question":"What are the equivalents or alternatives to SN74AS74AN?","answer":"The closest functional equivalent in a different logic family is the 74F74PC (Fairchild/ON Semiconductor), which is also a dual D-type positive-edge-triggered flip-flop in a 14-pin DIP, with a similar 80 MHz clock frequency and 10 ns propagation delay at 5 V. The 74F part has lower output drive (1 mA source, 20 mA sink) and higher quiescent current (about 20 mA). For a lower-speed, lower-power alternative, the SN74LS74AN (74LS family) is pin-compatible and widely available. No exact second-source with the same 74AS speed grade is listed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AS74AN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AS74AN when reusing this data.
