70 MHz clock and 31 ns propagation delay
The SN74HC374PWR is an octal D-type flip-flop from the 74HC family, clocked at 70 MHz with a maximum propagation delay of 31 ns at 6 V and 50 pF load. This timing budget determines the maximum data rate through the register — at 70 MHz the clock period is 14.3 ns, so the 31 ns delay means the output settles after the next clock edge, limiting the part to pipelined or registered applications where the delay is absorbed by the downstream logic.
Supply voltage and temperature grade
Runs on a 2 V to 6 V supply rail, covering standard 3.3 V and 5 V logic levels without a separate level translator. The -40°C to 85°C ambient temperature range suits industrial control cabinets and outdoor telecom equipment — the 74HC family's CMOS inputs draw only 8 µA quiescent current, so the thermal budget is dominated by the output load, not the device itself. Outputs source and sink 7.8 mA each, enough to drive a standard TTL load or a low-power LED indicator, but not a relay coil or high-capacitance bus without a buffer.
Tri-state output and package fit
Tri-state, non-inverted outputs let the device share a data bus with other peripherals — the output enable pin pulls all eight outputs into high-impedance state, allowing multiple flip-flops to drive the same bus lines without contention. Housed in a 20-TSSOP (4.40 mm wide) surface-mount package, the 0.65 mm pin pitch requires standard PCB assembly processes; the footprint is common across the 74HC logic family.
