FEA TURES
•Multiple V
CC
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
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 (nOE
1, 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.
