Product details

8-bit register with 125 MHz edge rate

The SN74F377AN is an 8-bit D-type flip-flop from TI's 74F family, clocked at 125 MHz with a 9 ns max propagation delay at 5V into a 50 pF load. Each of the eight flip-flops captures the D input on the rising clock edge and holds it until the next clock—standard parallel-register behavior, but at a clock rate that keeps up with fast bus interfaces in 5V systems.

5V supply, 0-70°C — the commercial workhorse envelope

If your board lives in a conditioned space, this is the right temp grade. Quiescent current sits at 72 mA, which is typical for a 74F part running all eight bits at speed. The output drive is asymmetric: 1 mA source, 20 mA sink—so it drives a bus or LED load on the low side but won't push much current high. Plan your pull-ups accordingly.

Active production, DIP-20 package

ROHS3 compliant, so it meets current European and global restrictions on hazardous substances. No special compliance documentation beyond the standard TI datasheet and RoHS certificate—nothing exotic to chase down for an audit.
