SN54AS286 具有总线驱动器奇偶校验 I/O 端口的 9 位奇偶校验发生器/校验器
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 () control input is implemented specifically to accommodate cascading. When is low, the parity tree is disabled and PARITY ERROR remains at a high logic level regardless of the input levels. When 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
