Overview
Philips Semiconductors Product specification 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.
