DG442CY+

Overview

The DG442CY+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally open switches with an on-resistance of 85 ohms maximum and an on-resistance match of 4 ohms maximum between channels. The device operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical parameters include a turn-on time of 250ns maximum, a turn-off time of 170ns maximum, and charge injection of 10pC maximum. It supports rail-to-rail signal handling and offers low off-leakage current of less than 5nA at +85°C. The component is housed in a 16-pin Narrow SO package and functions within a temperature range of 0°C to +70°C.

Feature Summary

Improved on-resistance matching between channels for enhanced signal integrity
Guaranteed on-resistance flatness over the entire signal range
Low power consumption suitable for battery-operated systems
High electrostatic discharge tolerance per Method 3015.7

Applications

Sample-and-hold circuits
Audio-signal routing
Test equipment
Communication systems

Procurement Notes

Verify the ordering suffix matches the required specifications. The plus symbol indicates lead-free packaging compliance. Confirm the temperature grade corresponds to the application environment. Ensure the package type aligns with the board layout requirements. Cross-reference the manufacturer part number with official distributor catalogs to confirm authenticity.

Selection Notes

Select this component when a quad SPST configuration is required with low on-resistance. Consider the operating voltage range to ensure compatibility with the system power supply. Evaluate the thermal performance if operating near the upper temperature limit. Compare switching speeds against system timing requirements. Verify logic level compatibility with the control interface.

Part Context

This device belongs to the DG441/DG442 series of improved analog switches. It serves as a direct replacement for industry-standard DG442 devices while offering enhanced performance characteristics. The series includes variants with different temperature ranges and package options. The DG442 variant specifically provides normally open switches, distinguishing it from the DG441 which offers normally closed switches.
