74ACT11544 - Texas Instruments

74ACT11544 OCTAL REGISTERED TRANSCEIVER

This 8-bit 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 (GAB or GBA) inputs are provided for each register to permit independent control in either direction of data flow. The 74ACT11544 inverts data in both directions. DW PACKAGE (.

Features

he A-to-B enable (CEAB) input must be low in order to enter data from A or to output data to B. Having CEAB low and LEAB low makes the A-to-B latches transparent; a subsequent low-to-high transition of LEAB puts the A latches in the storage mode. With CEAB and GAB 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 CEBA, LEBA, and GBA inputs. The 74ACT11544 is characterized for operation from
  – 40°C to 85°C. FUNCTION TABLE INPUTS CEAB LEAB GAB LATCH STATUS A TO B† OUTPUT BUFFERS B.
