DG528/DG529 19-3519 Rev 0 3/91 8-Channel Latchable Multiplexers General Description Features Maxims DG528/DG529 are monolithic, 8-channel, Low-Power, Monolithic CMOS Design CMOS multiplexers with on-board address and control On-Board Address Latches latches that simplify design and reduce board space in microprocessor-based applications. The DG528 is a Break-Before-Make Input Switches single-ended, 1-of-8 multiplexer, while the DG529 is a TTL and CMOS Logic Compatible differential, 2-of-8 multiplexer. These devices can oper- ate as multiplexers or demultiplexers. Microprocessor-Bus Compatible The DG528/DG529 have break-before-make switching r < 400 DS(ON) to prevent momentary shorting of the input signals. Each device operates with dual supplies (4.5V to Pin and Electrically Compatible with the Industry- 20V) or a single supply (+5V to +30V). All logic inputs Standard DG528/DG529 and ADG528/ADG529 are TTL and CMOS compatible. The Maxim DG528/DG529 are pin and electrically compatible with the industry-standard DG528/DG529.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
