FAST AND LS TTL DATA
QUAD 2-PORT REGISTER
The MC54/74F398 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-
flops on the rising edge of the clock.
Select Inputs from Two Data Sources
Fully Positive Edge-Triggered Operation
