DESCRIPTION
The 74ABT162245A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed. The 74ABT162245A device is a 16-bit transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features two Output Enable (1OE, 2OE) inputs for easy cascading and two Direction (1DIR, 2DIR) inputs for direction control. The 74ABT162245A is designed with 30 ohm series resistance in both the upper and lower output structures on both A and B ports. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus receiver/transmitters. The 74ABT162245A is the same as the 74ABT16245A-1. The part number has been changed to reflect industry standards Two options are available, 74ABT162245A which does not have the bus hold feature and the 74ABTH162245A which incorporates the bus hold feature. CONDITIONS Tamb = 25C; GND = 0V
* Same part as 74ABT16245A-1 * 74ABTH162245A incorporates bus hold data inputs which
eliminate the need for external pull-up resistors to hold unused inputs
* Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs

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. 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 = 5 10% a transition time of up to 100 sec is permitted. 4. This is the bus hold overdrive current required to force the input to the opposite logic state.
