It captures data on the positive edge of the clock. ## 40 MHz clock and 47 ns propagation delay — timing margin for the bus The 40 MHz clock frequency and 47 ns max propagation delay at 5.5 V with 150 pF load define the timing budget. The 6 mA source/sink drive is enough for a single TTL load. ## Industrial temperature range and active lifecycle Rated for -40°C to 85°C ambient, this part fits industrial control cabinets, outdoor telecom gear, and automotive cabin electronics (non-AEC). The lifecycle status is Active and ROHS3 compliant — no LTB risk, no end-of-life clock ticking. It is a current-production part available through independent distribution, quoted to order against an RFQ.","metaTitle":"SN74HCT574PWR D-Type Flip-Flop, 40 MHz, 20-TSSOP","metaDescription":"TI SN74HCT574PWR 8-bit D-type flip-flop with tri-state outputs. 40 MHz clock, 47 ns propagation delay, 4.5-5.5 V supply.
