Maxim’s DG528/DG529 are monolithic, 8-channel, CMOS multiplexers with on-board address and control latches that simplify design and reduce board space in microprocessor-based applications. The DG528 is a single-ended, 1-of-8 multiplexer, while the DG529 is a differential, 2-of-8 multiplexer. These devices can operate as multiplexers or demultiplexers. The DG528/DG529 have break-before-make switching to prevent momentary shorting of the input signals. Each device operates with dual supplies (±4.5V to ±20V) or a single supply (+5V to +30V). All logic inputs are TTL and CMOS compatible. The Maxim DG528/DG529 are pin and electrically compatible with the industry-standard DG528/DG529.
The Maxim DG528 (single‑ended 1‑of‑8) and DG529 (differential 2‑of‑8) are monolithic 8‑channel CMOS multiplexers with on‑board address latches and break‑before‑make switching. They operate from dual supplies (±4.5 V to ±20 V) or a single supply (+5 V to +30 V) and accept both TTL and CMOS logic levels.
The datasheet provides pin configurations, absolute maximum ratings, electrical characteristics, timing diagrams, package dimensions, and ordering information for multiple package types (DIP, SO, PLCC, LCC, etc.).
