It operates across a 2V to 6V supply range and delivers 24 mA of output drive current per channel. Housed in a 20-pin PDIP (0.300\" body width), this through-hole package suits breadboard prototyping, legacy socketed designs, or boards where rework access matters more than board density. ## Timing and drive margins at 5V Maximum propagation delay is 9.5 ns at 5V with a 50 pF load, so the data-to-output path settles well within a 6.45 ns clock period at 155 MHz — the limiting factor is the setup/hold window at the receiver, not the flip-flop's own delay. The 24 mA symmetrical source/sink drive at the outputs can directly switch a 5V logic input or a small relay coil through a series resistor, reducing the need for a separate line driver in low-power control paths. Quiescent current is only 4 µA, making this part viable for battery-backed logic sections that must hold state during sleep without draining the rail.","metaTitle":"SN74AC374N Texas Instruments 74AC D-Type Flip-Flop, 155 MHz","metaDescription":"SN74AC374N 74AC series octal D-type flip-flop, 155 MHz clock, 2V-6V supply, 24mA output drive, -40°C to +85°C, 20-DIP.
