(4 PCS) 54F399DM FSC Multiplexer/Register 1-Element Bipolar 8-IN 20-Pin CDIP
Tax included.
THIS LISTING IS FOR (4 PCS) OF 54F399DM BY FAIRCHILD SEMICONDUCTOR
54F399DM FSC Multiplexer/Register 1-Element Bipolar 8-IN 20-Pin CDIP
54F/74F398 # 54F/74F399
Quad 2-Port Register
General Description
The 'F398 and 'F399 are the logical equivalents of a quad
2-input multiplexer feeding into four edge-triggered flipflops.
A common Select input determines which of the two
4-bit words is accepted. The selected data enters the flipflops
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
Y Select inputs from two data sources
Y Fully positive edge-triggered operation
Y Both true and complement outputsÐ'F398
Y Guaranteed 4000V minimum ESD protectionÐ'F399
