The inverted outputs feed a tri-state bus — the /OE pin floats the bus when pulled high, so multiple registers can share a data line without contention. Output drive is rated 24 mA source and sink per pin, enough to drive a 50 pF load with a 10.5 ns propagation delay at 5 V. The 4 µA quiescent current keeps the static draw negligible in battery-backed or always-on rails. The 4.5 pF input capacitance is low enough that a single clock source can fan out to several loads without a dedicated buffer. ## Industrial temperature grade and package fit The 20-TSSOP body (4.40 mm width, 0.65 mm pitch) is a common footprint; the PCB land pattern matches the standard TSSOP-20 IPC-7351 nominal.","metaTitle":"SN74ACT564PW D-Type Flip-Flop, 90 MHz, 20-TSSOP","metaDescription":"Texas Instruments SN74ACT564PW D-type flip-flop, 8-bit, tri-state inverted outputs, 90 MHz clock, 24 mA drive, -40 to 85°C, active production.
