74F398 - Registers

Description

The 74F398 and 74F399 are the logical equivalent of a quad 2-input multiplexer feeding into four edge-triggered flip-flops.

A common Select input determines which of two 4-bit words is accepted.

The selected data enters the flip-flops on the rising edge of the clock.

Features

  • 74F398.
  • ,74F399.
  • Select inputs from two data sources.
  • Fully positive edge-triggered.
  • Both True and Complementary outputs.
  • 74F398.
