General Description

The 'F398 and 'F399 are the logical equivalents 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 'F399 is the 16-pin version of the 'F398, with only the Q outputs of the flip-flops available.

Features

  • Select inputs from two data sources
  • Fully positive edge-triggered operation
  • Both true and complement outputs-'F398
  • Guaranteed 4000V minimum ESD protection-'F399
