9-Bit Parity Generator/Checker

DM74AS280 9-Bit Parity Generator/Checker October 1986 Revised March 2000 DM74AS280 9-Bit Parity Generator/Checker 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 DM74AS280 can be used to upgrade the performance of most systems utilizing the ’180 parity generator/checker. Although the DM74AS280 is implemented without expander inputs, the corresponding function is provided by the availability of an input at pin 4 and no internal connection at pin 3. This permits the DM74AS280 to be substituted for the ’180 in existing designs to produce identical function even if DM74AS280s are mixed with existing ’180s. Features 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 Advanced oxide-isolated, ion-implanted Schottky TTL process s Switching specifications at 50 pF s Switching specifications guaranteed over full temperature and VCC range Ordering Code: Order Number DM74AS280M DM74AS280N Package Number M14A N14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available i.
