DESCRIPTION

The 74ABT541 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.

The 74ABT541 device is an octal buffer that is ideal for driving bus
lines. The outputs are all capable of sinking 64mA and sourcing
32mA. The device features input and outputs on opposite sides of
the package to facilitate printed circuit board layout.

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 3.4V.

3. This parameter is valid for any VCC between 0V and 2.1V with a transition time of up to 10msec. For VCC = 2.1V to VCC = 5V  10%, a
transition time of up to 100µsec is permitted.
