具有三态输出的八路寄存收发器
This 8-bit registered transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate latch enable or and output enable or inputs are provided for each register to permit independent control in either direction of data flow. The inverts data in both directions.
The A-to-B enable input must be low in order to enter data from A or to output data to B. Having low and low makes the A-to-B latches transparent; a subsequent low-to-high transition of puts the A latches in the storage mode. With and both low, the 3-state B outputs are active and reflect the data present at the output of the A latches. Data flow from B-to-A is similar, but requires the use of , , and inputs.
The 74ACT11544 is characterized for operation from -40°C to 85°C.
