Overview
The PS509LEX is a CMOS analog multiplexer featuring four differential channels or two dual single-ended channels. It operates on a single supply from 10 V to 36 V, or dual supplies ranging from ±5 V to ±18 V. The device provides rail-to-rail signal handling with an on-resistance of 125 Ω and low input leakage of 30 pA. Transition time is specified at 171 ns, while the enable turn-on time reaches 210 ns. It utilizes a 16-pin TSSOP package and includes break-before-make switching action.
Feature Summary
- Supports differential 4:1 or dual 4:1 single-ended channel configurations
- Compatible with both symmetric and asymmetric power supply topologies
- Features TTL-logic compatible digital inputs for broad logic integration
- Includes break-before-make switching to prevent signal shorting
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 against official Diodes Incorporated documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the selected component meets all required environmental standards and lead-free compliance criteria before finalizing procurement orders.
Selection Notes
Select the PS509LEX when differential signal routing or dual single-ended paths are required within a 16-pin footprint. Confirm that the system voltage range aligns with the 10 V to 36 V single-supply or ±5 V to ±18 V dual-supply limits. Verify that the 125 Ω on-resistance and 171 ns transition time satisfy the application's bandwidth and accuracy requirements.
Part Context
The PS509LEX belongs to the PS508/PS509 family of precision analog multiplexers manufactured by Diodes Incorporated. This series is designed for high-performance signal routing in industrial and measurement environments. The L suffix specifically denotes the 16-pin TSSOP package variant within this product line.
Replacement Considerations
The PS508LEX serves as the single-ended counterpart within the same family. Cross-reference the pinout and channel configuration to ensure compatibility if substituting between the PS508 and PS509 variants.
FAQ
Can the PS509 operate with unsymmetric power supplies?
Yes, the datasheet confirms it performs well with unsymmetric supplies, such as VDD = 12V and VSS = –5V.
What is the maximum operating temperature for this component?
The maximum operating temperature is +125°C.
How does the PS509 handle channel switching to prevent signal overlap?
It features a break-before-make switching action, which ensures one channel disconnects before the next connects.
