DESCRIPTION
The 74ABT651 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT651 transceiver/register consists of bus transceiver circuits with 3-State outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes HIGH. Output Enable (OEAB, OEBA) and Select (SAB, SBA) pins are provided for bus management. The following examples demonstrate the four fundamental bus-management functions that can be performed with the 74ABT651. The select pins determine whether data is stored or transferred through the device in real time. The output enable pins determine the direction of the data flow.

HIGH voltage level LOW voltage level Don't care LOW-to-HIGH clock transition The data output function may be enabled or disabled by various signals at the OEBA and OEAB inputs. Data input functions are always enabled, i.e., data at the bus pins will be stored on every LOW-to-HIGH transition of the clock. If both Select controls (SAB and SBA) are LOW, then clocks can occur simultaneously. If either Select control is HIGH, the clocks must be staggered in order to load both registers.

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 150 C. 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 3.4 V. 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 0 V and 2.1 V, with a transition time of up to 10 msec. From VCC = 2.1 V to VCC = 5 V 10%, a transition time of up to 100 sec is permitted.
