Quad 2-Port Register
General Description
The 74F398 and 74F399 are the logical equivalents of a
quad 2-input multiplexer feeding into four edge-triggered
flip-flops. A common Select input determines which of the
two 4-bit words is accepted. The selected data enters the
flip-flops on the rising edge of the clock. The 74F399 is the
16-pin version of the 74F398, with only the Q outputs of the
flip-flops available.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
