description

The SN54AS286 and SN74AS286 universal 9-bit
parity generators/checkers feature a local output
for parity checking and a 48-mA bus-driving
parity input/output (I/O) port for parity
generation/checking. The word-length capability
is easily expanded by cascading.
The transmit (XMIT) control input is implemented
specifically to accommodate cascading. When
XMIT is low, the parity tree is disabled and
PARITY ERROR remains at a high logic level
regardless of the input levels. When XMIT is high,
the parity tree is enabled. PARITY ERROR
indicates a parity error when either an even
number of inputs (A−I) are high and PARITY I/O
is forced to a low logic level, or when an odd
number of inputs are high and PARITY I/O is
forced to a high logic level.
The I/O control circuitry was designed so that the I/O port remains in the high-impedance state during power up
or power down to prevent bus glitches.
The SN54AS286 is characterized for operation over the full military temperature range of −55°C to 125°C. The
SN74AS286 is characterized for operation from 0°C to 70°C.
