QUAD 2-PORT REGISTER
The MC54/74F399 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. The MC54/74F399 is the 16-pin version
of the MC54/74F398, with only the Q outputs of the flip-flops available.
• Select Inputs from Two Data Sources
• Fully Positive Edge-Triggered Operation
