SN74AS286

具有總線驅(qū)動(dòng)器奇偶校驗(yàn) I/O 端口的 9 位奇偶校驗(yàn)發(fā)生器/校驗(yàn)器; ? Generate Either Odd or Even Parity forNine Data Lines? Cascadable for n-Bit Parity? Direct Bus Connection for Parity Generation or Checking byUsing the Parity I/O Port? Glitch-Free Bus During Power Up/Down? Package Options Include Plastic Small-Outline (D) Packages,Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic(J) 300-mil DIPs;

The SN54AS286 and SN74AS286 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.\nThe 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.\nThe 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.\nThe 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.\n?\n?\n?\n \n
