The MC10H164 is designed to be used in data multiplexing and parallel to serial conversion applications. Full parallel gating provides equal delays through any data path. The MC10H164 incorporates an output buffer, eight inputs and an enable. A high on the enable forces the output low. The open emitter output allows the MC10H164 to be connected directly to a data bus. The enable line allows an easy means of expanding to more than 8 lines using additional MC10H164's.
