DG509ABK

Overview

The DG509ABK is a monolithic CMOS analog multiplexer featuring two differential 4-channel (2-of-8) switching circuits. It operates on dual supplies ranging from ±4.5V to ±18V and guarantees break-before-make switching without latch-up. The device provides symmetrical, bidirectional operation with TTL and CMOS compatible logic inputs. Electrical specifications include a maximum drain-source on-resistance of 450Ω, source off-leakage current of 1nA, and drain off-leakage current of 5nA at +25°C. Switching times are characterized by a transition time of 1µs, enable turn-on time of 1.5µs, and enable turn-off time of 1µs. The component is housed in a 16-pin CERDIP package and supports an operating temperature range of -20°C to +85°C.

Feature Summary

Monolithic CMOS design ensuring low power consumption and latchup-proof construction
Guaranteed break-before-make switching for reliable signal routing
Symmetrical, bidirectional operation compatible with single or dual supply voltages
Logic and enable inputs that are fully compatible with both TTL and CMOS standards

Applications

Control Systems
Data Logging Systems
Aircraft Heads-Up Displays
Data-Acquisition Systems
Signal Routing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. Confirm RoHS compliance status as standard CERDIP packages may differ from lead-free variants. Cross-reference the part number with the latest datasheet revision history to ensure availability of updated electrical characteristics and pin configurations before finalizing procurement.

Selection Notes

Select this component when designing systems requiring differential signal multiplexing with guaranteed break-before-make timing. Ensure the application voltage falls within the ±4.5V to ±18V continuous operation range. Verify that the required operating temperature aligns with the -20°C to +85°C specification. Consider the 16-pin CERDIP footprint constraints during PCB layout planning.

Part Context

The DG509ABK belongs to the DG508A/DG509A family of monolithic CMOS analog multiplexers manufactured by Maxim Integrated. While the DG508A provides a single 8-channel configuration, the DG509A variant specifically offers two differential 4-channel circuits. This family serves as a plug-in upgrade for industry-standard equivalents, offering improved switching speeds and lower leakage currents compared to legacy designs.
