Quad 2-Port Register
General Description
The AC/ACT399 is the logical equivalent 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-flop on
the rising edge of the clock.
Features
s ICC reduced by 50%
s Select inputs from two data sources
s Fully positive edge-triggered operation
s Outputs source/sink 24 mA
s AC/ACT399 has TTL-compatible inputs

Functional Description
The AC/ACT399 is a high-speed quad 2-port register. It
selects 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.
