FEATURES
•Multiple VCC and GND pins minimize switching noise
•Live insertion/extraction permitted
•3-State output buffers
•Power-up 3-State
•74ABTH16827A 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 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model
DESCRIPTION
The 74ABT16827A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT16827A 20-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, 74ABT16827A which does not have the bus-hold feature and 74ABTH16827A which incorporates the bus-hold feature.
