74ABT899  
9-Bit Latchable Transceiver  
with Parity Generator/Checker  
Ability to simultaneously generate and check parity  
General Description  
May be used in systems applications in place of the  
543 and 280  
The ABT899 is a 9-bit to 9-bit parity transceiver with trans-  
parent latches. The device can operate as a feed-through  
transceiver or it can generate/check parity from the 8-bit  
data busses in either direction.  
May be used in system applications in place of the  
657 and 373 (no need to change T/R to check parity)  
Guaranteed output skew  
The ABT899 features independent latch enables for the A-  
to-B direction and the B-to-A direction, a select pin for  
ODD/EVEN parity, and separate error signal output pins for  
checking parity.  
Guaranteed multiple output switching specifications  
Output switching specified for both 50 pF and  
250 pF loads  
Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
Features  
Latchable transceiver with output sink of 64 mA  
Guaranteed latchup protection  
Option to select generate parity and check or  
High impedance glitch free bus loading during entire  
“feed-through” data/parity in directions A-to-B or B-to-A  
power up and power down cycle  
Independent latch enables for A-to-B and B-to-A  
Nondestructive hot insertion capability  
directions  
Disable time less than enable time to avoid bus  
Select pin for ODD/EVEN parity  
contention  
ERRA and ERRB output pins for parity checking
