‡ Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are  bserved.

The 54ACT11470 is an 8-bit registered bus
transceiver that contains two sets of D-type flip-flops for temporary storage of data flowing in either direction. Separate clock (CLKAB or CLKBA) and output-enable (OEAB or OEBA) inputs of 54ACT11470 are provided for each register to permit independent control in either direction of data flow.

The A-to-B enable (CEAB) input of 54ACT11470 must be low in order to enter data from A or to output data to B. If both CEAB and CLKAB are low, then the B port presents the level of the A port prior to the most recent low-to-high transition of CLKAB. Data flow from B to A is similar, but requires the use of CEBA, CLKBA, and OEBA inputs.

To avoid false clocking of the flip-flops, CEAB and CEBA should not be switched from low to high while CLK is low.

The 54ACT11470 is characterized for operation over the full military temperature range of 55°C to 125°C. The 74ACT11470 is characterized for operation from 40°C to 85°C.
