Transceivers/Registers
General Description
These devices consist of bus transceiver circuits with D-
type flip-flops, and control circuitry arranged for multiplexed
transmission of data directly from the input bus or from
internal registers. Data on the A or B bus will be clocked
into the registers as the appropriate clock pin goes to HIGH
logic level. Output Enable pins (OEAB, OEBA) are pro-
vided to control the transceiver function.
