74F399 - Quad 2-Port Register

Download the 74F399 datasheet PDF. This datasheet also covers the 74F399PC variant, as both devices belong to the same quad 2-port register family and are provided as variant models within a single manufacturer datasheet.

Description

The ’F398 and ’F399 are the logical equivalents of a quad 2-input multiplexer feeding into four edge-triggered flipflops A common Select input determines which of the two 4-bit words is accepted The selected data enters the flipflops on the rising edge of the clock The ’F399 is the 16-pin version of
