DM74AS286  
9-Bit Parity Generator/Checker  
with Bus-Driver Parity I/O Port  
General Description  
Features  
■ PNP inputs to reduce bus loading  
These universal, 9-bit parity generators/checkers utilize  
advanced Schottky high performance circuitry and feature  
odd/even outputs to facilitate operation of either odd or  
even parity applications. The word length capability is eas-  
ily expanded by cascading.  
■ Generates either odd or even parity for nine data lines  
■ Inputs are buffered to lower the drive requirements  
■ Can be used to upgrade existing systems using MSI  
parity circuits  
The DM74AS286 can be used to upgrade the performance  
of most systems utilizing the DM74AS280 parity generator/  
checker. Although the DM74AS286 is implemented without  
expander inputs, the corresponding function is provided by  
the availability of an input pin XMIT. XMIT is a control line  
which makes parity error output active and parity an input  
port when HIGH; when LOW, parity error output is inactive  
and parity becomes an output port. In addition, parity I/O  
control circuitry contains a feature to keep the I/O port in  
the 3-STATE during power UP or DOWN to prevent bus  
glitches.  
■ Cascadable for n-bits  
■ Switching specifications at 50 pF  
■ Switching specifications guaranteed over full  
temperature and VCC range  
■ A parity I/O portable to drive bus
