FEATURES

•Multiple VCC and GND pins minimize switching noise

•Live insertion/extraction permitted

•3-State output buffers

•Power-up 3-State

•74ABTH16825A incorporates bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs

•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

QUICK REFERENCE DATA

DESCRIPTION

The74ABT16825A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

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.

Two options are available, 74ABT16825A which does not have the bus-hold feature and 74ABTH16825A which incorporates the bus-hold feature.
