具有三态输出的八路寄存收发器 24-SSOP 0 to 70
The SN74F543 octal 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 A outputs are characterized to sink 24 mA while the B outputs are characterized to sink 64 mA.
The A-to-B enable input must be low in order to enter data from A or to output data from 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 using the , , and inputs.
The SN74F543 is available in "s shrink small-outline package DB, which provides the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN74F543 is characterized for operation from 0°C to 70°C.
A-to-B data flow is shown; B-to-A flow control is the same except that it uses , , and .
