74ABT544
Octal latched transceiver with dual enable; inverting; 3-state
Rev. 04 -- 15 January 2009 Product data sheet
1. General description
The 74ABT544 high performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT544 octal latched transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate latch enable (LEAB, LEBA) and output enable (OEAB, OEBA) inputs are provided for each register to permit independent control of data transfer in either direction. The outputs are guaranteed to sink 64 mA.

6.2 Description
The 74ABT544 contains two sets of eight D-type latches, with separate control pins for each set. Using data flow from A-to-B as an example, when the A-to-B enable (EAB) input, the A-to-B latch enable (LEAB) input and the A-to-B output enable (OEAB) input are all LOW, the A-to-B path is transparent. A subsequent LOW-to-HIGH transition of the LEAB signal puts the A data into the latches where it is stored and the B outputs no longer change with the A inputs. With EAB and OEAB both LOW, the 3-state B output buffers are active and display the data present at the outputs of the A latches. Control of data flow from B-to-A is similar, but using the EBA, LEBA, and OEBA inputs.

The input and output voltage ratings may be exceeded if the input and output current ratings are observed. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 C.

For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power. This parameter is valid for any VCC between 0 V and 2.1 V, with a transition time of up to 10 ms. From VCC = 2.1 V to VCC = 5 V 10 %, a transition time of up to 100 ms is permitted. Not more than one output should be tested at a time, and the duration of the test should not exceed one second. This is the increase in supply current for each input at 3.4 V.
