Overview
The PI5A4624TEX is a single-pole, double-throw (SPDT) analog switch manufactured by Diodes Incorporated in a compact 6-pin SOT23 package. It operates on a single supply voltage ranging from +1.8V to +5.5V. The device features a maximum on-resistance of 1 ohm at +5V, 2 ohms at +3V, and 4 ohms at +2.5V. Switching times are specified as 50ns maximum for both turn-on and turn-off intervals. Input leakage current is limited to 4nA at 25°C, with power consumption at 5μW. Off-isolation reaches -57dB at 1MHz.
Feature Summary
- Direct replacement for MAX4624 with improved electrical specifications
- Break-before-make switching action guaranteed
- Compatible with TTL and CMOS logic families
Applications
- Audio and video signal routing
- Communication circuits
- Portable battery-operated equipment
- Data acquisition systems
- Relay replacement
Procurement Notes
Verify the ordering suffix 'TEX' corresponds to the tape and reel packaging format. Confirm that the component meets Pb-free and Green environmental standards as indicated in the manufacturer's documentation. Ensure compatibility with the intended operating voltage range between 1.8V and 5.5V before finalizing procurement.
Selection Notes
Select this component when space constraints require a 6-pin SOT23 footprint. Choose based on required on-resistance levels at specific supply voltages. Verify logic input thresholds match the system's high and low voltage definitions. Consider the break-before-make characteristic if signal overlap must be prevented during switching transitions.
Part Context
This part belongs to the PI5A46xx series of low-voltage SPDT switches. It serves as an enhanced successor to the MAX4624, offering lower on-resistance and faster switching speeds. The TEX suffix denotes the specific tape and reel packaging configuration used for automated assembly processes.
Replacement Considerations
The datasheet explicitly identifies the PI5A4624 as an improved direct replacement for the MAX4624. Verify pinout compatibility and ensure the new device's on-resistance characteristics meet or exceed the original design requirements.
FAQ
What is the maximum on-resistance at a 3.3V supply?
At a +3.3V supply, the maximum on-resistance is 2 ohms.
Does the PI5A4624 support break-before-make switching?
Yes, break-before-make switching is guaranteed for the PI5A4624.
What is the input leakage current specification?
The input leakage current is 4nA maximum at 25°C.
