FUNCTIONAL DESCRIPTION
The SN54/74LS398 and SN54/74LS399 are high-speed
Quad 2-Port Registers. They select four bits of data from two
sources (Ports) under the 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 in-
put (CP). The 4-Bit RS type output register is fully edge-trig-
gered. The Data inputs (I) and Select inputs (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
SN54/74LS398 has both Q and Q Outputs available.
