1998 Feb 27
853-1824 19025
FEATURES
Multiple V
CC
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.
