power dissipation with high speed and high  
output drive.  
sent to the input of a storage register. If a  
Low–to–High transition happens at the clock  
input (CP), the error data is stored in the  
register and the Open–collector error flag  
(ERROR) will go Low. The error flag register  
is cleared with a Low pulse on the CLEAR  
input.  
FEATURES  
Low static and dynamic power dissipation  
The 74ABT834 is an octal inverting  
transceiver with a parity generator/checker  
and is intended for bus–oriented applications.  
with high speed and high output drive  
Open–collector ERROR output  
Output capability: +64mA/–32mA  
When Output Enable A (OEA) is High, it will  
place the A outputs in a high impedance  
state. Output Enable B (OEB) controls the B  
outputs in the same way.  
Latch–up protection exceeds 500mA per  
If both OEA and OEB are Low, data will flow  
from the A bus to the B bus and the part is  
forced into an error condition which creates  
an inverted PARITY output. This error  
condition can be used by the designer for  
system diagnostics.  
Jedec JC40.2 Std 17  
ESD protection exceeds 2000 V per MIL  
STD 883C Method 3015.6 and 200 V per  
Machine Model  
The parity generator creates an odd parity  
output (PARITY) when OEB is Low. When  
OEA is Low, the parity of the B port, including  
the PARITY input, is checked for odd parity.  
When an error is detected, the error data is
