Clock frequency reaches 115 MHz, with a max propagation delay of 10.6 ns at 5V into 50 pF — fast enough for most 8-bit bus applications below 100 MHz, where the setup/hold window at the receiver is the tighter constraint. ## Supply range and drive — fits mixed-voltage boards Operates across 2V to 5.5V, so the same BOM line covers a 3.3V microcontroller bus and a 5V legacy peripheral without a second voltage-domain part number. Output drive is 8 mA source and sink per pin — enough to light an LED directly or drive a 5V CMOS input, but plan for a buffer if the trace fans out to more than three loads at 115 MHz. Quiescent current sits at 4 µA typical — negligible in a powered system, but worth noting if the board spends time in standby with the clock gated. ## Industrial temperature and compliance ROHS3 compliant per the lifecycle record — no restricted substances in the package or lead finish, so it passes EU material declarations without exemption paperwork. Input capacitance is 4 pF per pin — a typical value for the 74VHC family; the total bus load adds up when eight inputs are tied to a single clock line, so check the driver's fan-out at 115 MHz.","metaTitle":"Toshiba 74VHC574FT D-Type Flip-Flop, 115 MHz, 20-TSSOP","metaDescription":"Toshiba 74VHC574FT octal D-type flip-flop, 115 MHz clock, 2-5.5V supply, 8mA drive, 20-TSSOP.
