Octal Registered Transceivers With 3-state Outputs

  The ?BCT544 octal registered Transceiver contains two sets of D-type Latches for temporary storage of data flowing in either direction. Separate latch-enable (LEAB or LEBA) and output-enable (OEAB or OEBA) inputs are provided for each Register to permit independent control in either direction of data flow. The A-to-B enable (CEAB) input must be low in order to enter data from A or to output data from B. If CEAB is low and LEAB is low, the A-to-B Latches are transparent; a subsequent low-to-high transition of LEAB puts the A Latches in the storage mode. With CEAB and OEAB both low, the 3-state B outputs are active and reflect the inverted data present at the output of the A Latches Data flow from B to A is similar, but requires using the CEBA, LEBA, and OEBA inputs. The SN54BCT544 is characterized for operation over the full military temperature range of ? 55?C to 125?C. The SN74BCT544 is characterized for operation from 0?C to 70?C.
