Product specification  
8-bit transceiver with 9-bit parity checker/  
generator and flag latch (3-State)  
74ABT853  
The 74ABT853 is an octal transceiver with a parity  
generator/checker and is intended for bus–oriented applications.  
FEATURES  
• Low static and dynamic power dissipation with high speed and  
high output drive  
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.  
• Open-collector ERROR output  
• Output capability: +64mA/–32mA  
• Latch-up protection exceeds 500mA per Jedec Std 17  
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 sent to the input of a latch. The error data  
can then be passed, stored, cleared, or sampled depending on the  
ENABLE and CLEAR control signals.  
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015  
and 200 V per Machine Model  
• Power-up 3-State  
• Live insertion/extraction permitted  
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.  
DESCRIPTION  
The 74ABT853 high-performance BiCMOS device combines low  
static and dynamic power dissipation with high speed and high  
output drive.
