Note 2: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation of FACT™ circuits outside databook specifications.


Description

The 74ACT652SC consists 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 of the 74ACT652SC on the A or B bus will be clocked into the registers as the appropriate clock pin goes to the HIGH logic level. Output Enable pins (OEAB, OEBA) are provided to control the transceiver function.
