With a 16 ns propagation delay at 5V and 50 pF load, the output settles within one clock period at 35 MHz, but the downstream logic must budget that delay into its timing closure. Output drive is rated 2.6 mA source, 24 mA sink — the sink current is nearly 10× the source, so this part drives heavy capacitive loads on the falling edge better than the rising edge. Quiescent supply current is 19 mA typical, which is modest for a bipolar 74ALS part but higher than a CMOS equivalent. ## Package and temperature — legacy footprint, commercial environment The 20-pin DIP (0.300\" width, 7.62 mm) through-hole package is a legacy footprint — it plugs into a standard breadboard or socket, but any migration to a surface-mount alternative (like the SN74LVC574APWT in TSSOP) requires a board layout change.","metaTitle":"SN74ALS374AN Texas Instruments D-Type Flip-Flop, 35 MHz","metaDescription":"SN74ALS374AN D-Type flip-flop, 35 MHz clock, 16ns prop delay, 4.5-5.5V, 20-DIP.
