DM74AS280
Overview
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.
- 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 in Tape and Reel.
