8-bit flip-flop with tri-state bus hold
The SN74AHCT374DW is an 8-bit D-type flip-flop from TI's 74AHCT logic family, featuring positive-edge triggering and tri-state non-inverted outputs for shared-bus architectures. It operates from a 4.5 V to 5.5 V supply, typical of the AHCT series which provides TTL-compatible input thresholds with CMOS output drive — a direct drop-in for 5 V legacy bus designs.
Timing and drive for 5 V bus interfaces
Rated clock frequency of 130 MHz means the flip-flop can latch data at that rate, but the real system timing is set by the 10.4 ns max propagation delay at 5 V and 50 pF load — budget this into your setup/hold margin for the downstream logic. Output drive is symmetrical at 8 mA source and sink (high and low), which is enough to drive a single TTL load or a short PCB trace but not a backplane — plan for a buffer if the fan-out exceeds a few standard loads. Input capacitance is 4 pF, so the clock line sees a modest load per device; multiple devices on the same clock tree still need attention to signal integrity at 130 MHz.
Industrial temperature and active lifecycle
Rated for -40°C to +85°C ambient, this part suits industrial control, telecom, and outdoor equipment that sees temperature swings — not just bench-top gear.
