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
Features
Y Select inputs from two data sources
Y Fully positive edge-triggered operation
Y Both true and complement outputs ’F398
Y Guaranteed 4000V minimum ESD protection
’F399
