54F/74F399
Quad 2-Port Register
General Description
The ’F398 and ’F399 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 ’F399 is the 16-pin
version of the ’F398, with only the Q outputs of the flip-flops
available.
