3.7 ns propagation delay — what it means for bus timing
The 74FCT162374ETPVG is a dual 8-bit D-type flip-flop from the 74FCT series, clocked on the positive edge with non-inverting tri-state outputs. Its 3.7 ns max propagation delay at 5 V and 50 pF load sets the data-to-output settling window — for a 50 MHz bus cycle (20 ns period), the output is valid within 18.5% of the cycle, leaving 16.3 ns for setup and hold at the receiver. This margin matters when the part sits in a fan-out buffer or pipeline register driving multiple loads. The 24 mA symmetrical output drive (both high and low) drives the specified 50 pF load without edge-rate degradation. On a heavily loaded backplane, the actual rise time depends on the total capacitance; the 3.5 pF input capacitance per channel keeps the loading on the driving stage low.
The 500 µA quiescent current is the standby draw when all outputs are static — the dynamic current scales with the clock frequency and output load, not this figure. The 48-BSSOP package (7.50 mm body width) is a standard SSOP footprint — board layout matches the JEDEC MO-118 variation.
Active lifecycle — no end-of-life concern
Renesas lists the 74FCT162374ETPVG as Active — no PCN, no last-time-buy window, no successor to track.
