Output drive is 24 mA source and sink — enough to light a small LED or drive a few CMOS inputs without a buffer, but not enough for a relay coil or a long twisted-pair run. Quiescent current sits at 4 µA, so the chip draws almost nothing when the clock is stopped and the outputs are static. Input capacitance is 4.5 pF per pin — factor that into the clock tree loading if you are running a high-speed bus with multiple loads on the same trace. ## Active production and compliance — what the procurement desk needs No lead-time number to share here — drop a quote request and we will come back with a date.","metaTitle":"SN74AC564DW 74AC D-Type Flip-Flop, 95 MHz, 20-SOIC","metaDescription":"Texas Instruments SN74AC564DW 8-bit D-type flip-flop, 95 MHz clock, 24 mA output, 2-6 V supply, -40 to 85°C, ROHS3.
