Octal Bus Transceivers and Registers
These devices consist of bus transceivers circuits, with 3-state or open-collector outputs, D-type
flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the data
bus or from the internal storage registers. Data on the A or B bus will be clocked into the registers
on the low-to-high transition of the appropriate clock pin (CAB or CBA). The following examples
demonstrate the four fundamental bus-management functions that can be performed with the octal
bus transceivers and registers.
