8-bit shift register with 2:1 mux-in, latched “B” inputs, and serial out
74F835
FEATURES
Specifically designed for Video applications Combines the 74F373, two 74F157s, and the 74F166 functions in Interleaved loading with 2:1 mux Dual 8-bit parallel inputs Transparent latch on all “B” inputs Guaranteed serial shift frequency to 100MHz Expandable to 16-bits or more with serial input
DESCRIPTION
The 74F835 is a high speed 8-bit parallel/serial-in, serial-out shift register whose parallel inputs have been connected to an internal octal two-to-one multiplexer with all the “B” inputs connected to an octal latch. This 24-pin part is specifically designed for video bit shifting, where interleaved loading is desired and parts count is critical. It is useful in any design where a 2:1 mux input with a transparent latch is needed. TYPICAL SUPPLY CURRENT (TOTAL) 45mA one package
