Product details

8-bit D-type register with 125 MHz clock ceiling

The SN74F377ADW: The positive-edge trigger and non-inverted outputs make it a straight-through register for buffering data on a synchronous bus.

Supply and temperature grade for commercial logic

Quiescent current is 72 mA typical; output drive is 1 mA source, 20 mA sink. The asymmetric drive means the output high level sags under load faster than the low level — budget the fan-out for the high-state current.

20-SOIC wide-body footprint

Housed in a 20-SOIC wide-body package (7.50 mm body width), the SN74F377ADW mates with standard SOIC-20W land patterns. The tube packaging is the standard through-distribution format for prototype and low-volume builds.

Frequently asked questions

What is the propagation delay of SN74F377ADW?

Maximum propagation delay is 9 ns at 5 V supply into a 50 pF load. This sets the timing budget for the data-to-output path in a synchronous system.

What package does SN74F377ADW come in?

20-SOIC wide-body (0.295 inch body width, 7.50 mm). The supplier device package is 20-SOIC, and it ships in tube packaging.
