DM74AS286 - 9-Bit Parity Generator/Checker with Bus-Driver Parity I/O Port

General Description

These universal, 9-bit parity generators/checkers utilize advanced Schottky high performance circuitry and feature odd/even outputs to facilitate operation of either odd or even parity applications.

The word length capability is easily expanded by cascading.

Key Features

  • s PNP inputs to reduce bus loading s Generates either odd or even parity for nine data lines s Inputs are buffered to lower the drive requirements s Can be used to upgrade existing systems using MSI parity circuits s Cascadable for n-bits s Switching specifications at 50 pF s Switching specifications guaranteed over full temperature and VCC range s A parity I/O portable to drive bus Ordering Code: Order Number DM74AS286M DM74AS286N Package Number M14A N14A Package.

DM74AS286 9-Bit Parity Generator/Checker with Bus-Driver Parity I/O Port October 1986 Revised April 2000 DM74AS286 9-Bit Parity Generator/Checker with Bus-Driver Parity I/O Port General Description These universal, 9-bit parity generators/checkers utilize advanced Schottky high performance circuitry and feature odd/even outputs to facilitate operation of either odd or even parity applications. The word length capability is easily expanded by cascading. The DM74AS286 can be used to upgrade the performance of most systems utilizing the DM74AS280 parity generator/ checker. Although the DM74AS286 is implemented without expander inputs, the corresponding function is provided by the availability of an input pin XMIT.
