3.3-V ABT OCTAL REGISTERED TRANSCEIVERS WITH 3-STATE OUTPUTS

These octal transceivers SN54LVT543 SN74LVT543 are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL Interface to a 5-V system environment. The LVT543 contain 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 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. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid Logic level By Texas Instruments
