74F398 • 74F399 Quad 2-Port Register April 1988 Revised August 1999 74F398 • 74F399 Quad 2-Port Register General Description Features The 74F398 and 74F399 are the logical equivalents of a � Select inputs from two data sources quad 2-input multiplexer feeding into four edge-triggered � Fully positive edge-triggered operation flip-flops. A common Select input determines which of the � Both true and complement outputs—74F398 two 4-bit words is accepted. The selected data enters the flip-flops on the rising edge of the clock. The 74F399 is the 16-pin version of the 74F398, with only the Q outputs of the flip-flops available.
