SN74AS286
- Generate Either Odd or Even Parity forNine Data Lines
- Cascadable for n-Bit Parity
- Direct Bus Connection for Parity Generation or Checking by Using 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-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.
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.
