54F 74F398 54F 74F399 Quad 2-Port Register
May 1995
54F 74F398 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 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 the 'F398 with only the Q outputs of the flip-flops available

Functional Description
The 'F398 and 'F399 are high-speed quad 2-port registers hey select four bits of data from either of two sources (Ports) under control of a common Select input (S) The selected data is transferred to a 4-bit output register synchronous with the LOW-to-HIGH transition of the Clock input (CP) The 4-bit D-type output register is fully edge-triggered The Data inputs (I0x I1x) and Select input (S) must be stable only a setup time prior to and hold time after the LOW-to-HIGH transition of the Clock input for predictable operation The 'F398 has both Q and Q outputs Inputs S I I h h I0 I h X X
