description
The ´BCT544 octal registered transceiver contains two sets ofD-type latches for temporary storage of data flowing in eitherdirection. Separate latch-enable (
or 
) andoutput-enable (
or ) inputs are provided for eachregister to permit independent control in either direction of dataflow.
The A-to-B enable (
)input must be low in order to enter data from A or to output datafrom B. If is low and is low, theA-to-B latches are transparent; a subsequent low-to-high transitionof puts the Alatches in the storage mode. With and both low, the3-state B outputs are active and reflect the inverted data present atthe output of the A latches. Data flow from B to A is similar, butrequires using the 
,, and inputs.
The SN54BCT544 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74BCT544 is characterized for operation from 0°C to 70°C.
