Overview
The DG401DYZ is a dual single-pole single-throw (SPST) normally-open analog switch manufactured by Renesas Electronics Corporation. It utilizes CMOS technology to provide low on-resistance and fast switching capabilities within a 16-pin SOIC surface-mount package. The device supports single supply voltages ranging from 5V to 34V or dual supplies from ±5V to ±17V. Key electrical parameters include a maximum on-resistance of 45 ohms, a channel-to-channel matching of 3 ohms, and a charge injection of 60pC. Switching times are specified at a maximum of 150ns for turn-on and 100ns for turn-off. The component operates within a temperature range of -40°C to 85°C.
Feature Summary
- CMOS construction ensures low power consumption and compatibility with TTL and CMOS logic levels.
- Bilateral switches allow for AC or bidirectional signal handling with minimal on-resistance variation over the input voltage range.
- Epitaxial layer integration prevents latch-up issues associated with older CMOS technologies.
Applications
- Sample and hold circuits
- Data acquisition systems
- Communication equipment
Procurement Notes
Verify RoHS compliance status carefully, as the standard DG401DY variant is explicitly noted as non-compliant in some distributor records. Confirm the specific suffix 'Y' indicates lead-free and halogen-free attributes per Renesas documentation before ordering. Check current manufacturing status, as this part number may be discontinued or superseded by newer revisions like the DG401DYZ.
Selection Notes
Select this component when dual SPST switching is required with moderate speed and low leakage. Ensure the supply voltage does not exceed the 34V single or ±17V dual limits. Consider the 45-ohm on-resistance for signal integrity requirements. Verify that the 16-SOIC package dimensions fit the PCB layout constraints compared to alternative packages.
Part Context
The DG401 belongs to the DG40x series of monolithic CMOS analog switches. It serves as a functional equivalent to earlier discrete solutions but offers integrated reliability. The device is part of a broader family including DG403 and DG405 variants, which differ primarily in configuration and pinout. Renesas continues to support this legacy interface category for industrial applications.
Replacement Considerations
The DG401DYZ is a direct replacement for the DG401DY. Cross-reference with Analog Devices/Maxim Integrated DG401DY+ for pin-compatible alternatives, noting potential differences in charge injection specifications between manufacturers.
