Overview
The PS508QEX is a CMOS analog multiplexer from Diodes Incorporated, featuring eight single-ended channels in a 16-pin QSOP package. It supports dual supplies of ±5V to ±18V or a single supply of 10V to 36V. Key electrical parameters include a maximum on-resistance of 200Ω at ±10V and 430Ω at +10V single supply. The device operates with a typical supply current of 135µA, transition time of 310ns, and input leakage current of 1nA. It provides rail-to-rail signal handling, TTL-compatible logic thresholds, and break-before-make switching action.
Feature Summary
- CMOS technology enabling low power consumption and high impedance signal switching
- TTL and CMOS logic compatibility for flexible digital control integration
- Break-before-make switching action to prevent signal shorting during channel transitions
- Rail-to-rail operation supporting wide analog signal ranges across various supply configurations
Applications
- Factory automation and industrial process controls
- Programmable Logic Controllers (PLC)
- Analog input modules
- ATE test equipment
- Digital multimeters
Procurement Notes
Verify the specific ordering suffix 'QEX' corresponds to the 16-pin QSOP package and tape/reel packaging format as defined in the manufacturer's ordering information. Confirm that the component meets RoHS 3 compliance and halogen-free requirements if mandated by project specifications. Ensure the selected variant matches the required thermal and mechanical constraints for the target assembly process.
Selection Notes
Select the PS508QEX when eight single-ended analog channels are required within a compact surface-mount footprint. This part is suitable for designs needing wide supply voltage flexibility and low charge injection. Verify that the maximum on-resistance and leakage current specifications meet the precision requirements of the signal path. Consider the QSOP package dimensions against available PCB real estate.
Part Context
The PS508QEX belongs to the PS508/PS509 family of precision analog multiplexers manufactured by Diodes Incorporated. While the PS508 provides eight single-ended channels, the companion PS509 offers differential or dual single-ended configurations. Both share identical pinouts and core electrical characteristics, differing primarily in internal channel topology.
Replacement Considerations
Direct functional replacements within the same family include PS508LEX and PS508WEX, which offer identical electrical performance in TSSOP and SOIC packages respectively. Cross-family substitution requires verification of pinout compatibility and on-resistance limits.
