FEATURES

DESCRIPTION

The74ABT16825A high-performance BiCMOS device combines low

static and dynamic power dissipation with high speed and high

output drive.

• Multiple V and GND pins minimize switching noise

CC

• Live insertion/extraction permitted

• 3-State output buffers

The74ABT16825A 18-bit buffers provide high performance bus

interface buffering for wide data/address paths or buses carrying

parity. They have NOR Output Enables (nOE1, nOE2) for maximum

control flexibility.

• Power-up 3-State

• 74ABTH16825A incorporates bus-hold data inputs which

eliminate the need for external pull-up resistors to hold unused

inputs

Two options are available, 74ABT16825A which does not have the

bus-hold feature and 74ABTH16825A which incorporates the

bus-hold feature.

• Output capability: +64mA/–32mA

• Latch-up protection exceeds 500mA per Jedec Std 17

• ESD protection exceeds 2000V per MIL STD 883 Method 3015

and 200V per Machine Model

• 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 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 V between 0V and 2.1V with a transition time of up to 10msec. From V = 2.1V to V = 5V ± 10% a

transition time of up to 100µsec is permitted.

4. Unused pins at V or GND.
