General Description
Features
n ICC reduced by 50%
The ’AC/ACT399 is the logical equivalent of a quad 2-input
multiplexer feeding into four edge-triggered flip-flops. A com-
mon 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.
n Select inputs from two data sources
n Fully positive edge-triggered operation
n Outputs source/sink 24 mA
n ACT399 has TTL-compatible inputs

Functional Description
Function Table
The ’AC/ACT399 is a high-speed quad 2-port register. It se-
lects four bits of data from either of two sources (Ports) un-
der 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 in-
puts (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.
