What the 250 MHz clock and 5.2 ns delay mean for your bus
The CY74FCT374CTSOC is a single 8-bit D-type flip-flop from Cypress's 74FCT family, clocked at 250 MHz with a propagation delay of 5.2 ns at 5 V and 50 pF load. That combination puts it in the fast-edge tier for 5 V logic — the 250 MHz clock rate supports high-speed data latching in memory interfaces or bus-register stages, while the 5.2 ns delay gives the timing budget for backplane traces or FPGA-to-peripheral links without adding a full clock cycle of pipeline latency. The tri-state, non-inverted outputs let multiple devices share a common data bus; the 32 mA sink / 64 mA source drive handles the fan-out of several downstream TTL loads without external buffers.
Industrial temperature range and supply tolerance
Rated for -40°C to 85°C ambient, this part fits industrial control cabinets, outdoor telecom gear, and factory-floor PLC racks where the enclosure temperature swings. The supply range of 4.75 V to 5.25 V covers the full 5 V ±5% tolerance band — common on legacy backplanes and regulated linear supplies. Input capacitance of 5 pF keeps the AC load light on the driving gate.
Lifecycle and sourcing
No end-of-life notice or last-time-buy window is recorded — this part can be specified into new designs without obsolescence risk.
