SN74AS286DRG4 Products

The SN54AS286 and SN74AS286DRG4 universal 9-bit parity generators/checkers feature a local output for parity checking and a 48-mA bus-drivingparity input/output (I/O) port for parity generation/checking. The word-length capability is easily expanded by cascading.

The transmit () control input is implemented specifically to accommodate cascading. Whenis low, the parity tree is disabled and PARITY ERROR remains at a high logic level regardless of the input levels. Whenis 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 SN74AS286DRG4 is characterized for operation from 0°C to 70°C.
