74ABT543A
FEATURES
* Combines 74ABT245 and 74ABT373 type functions in one device * 8-bit octal transceiver with D-type latch * Back-to-back registers for storage * Separate controls for data flow in each direction * Output capability: +64mA/-32mA * Live insertion/extraction permitted * Power-up 3-State * Power-up reset * Latch-up protection exceeds 500mA per Jedec Std 17 * ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
The 74ABT543A Octal Registered 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 64mA.
FUNCTIONAL DESCRIPTION
The 74ABT543A 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 and the A-to-B Latch Enable (LEAB) input are 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.
DESCRIPTION
The 74ABT543A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. 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 150C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES: 1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second. 2. This is the increase in supply current for each input at 3.4V. 3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power. 4. This parameter is valid for any VCC between 0V and 2.1V, with a transition time of up to 10msec. From VCC = 2.1V to VCC = 5V 10%, a transition time of up to 100sec is permitted.
