8-bit D-type register for 5 V bus latching
The Texas Instruments SN74HCT574PWR is an 8-bit D-type flip-flop with tri-state, non-inverted outputs in a 20-TSSOP package. 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.
