Overview
The PI5A3166TAEX is a single-pole single-throw (SPST) analog switch manufactured by Diodes Incorporated in a SOT23-5 package. It operates on a single supply voltage ranging from 1.65V to 5.5V, supporting rail-to-rail signal switching. The device features a maximum on-resistance of 1.9Ω at 1.65V and 1.2Ω at 4.5V. Key electrical parameters include a -3dB bandwidth of 200MHz, turn-on time of 2ns to 3ns, and turn-off time of 5ns to 9ns depending on the supply voltage. It exhibits low charge injection of 25pC to 35pC and high off-isolation of -70dB.
Feature Summary
- Supports low-voltage operation with a wide supply range from 1.65V to 5.5V
- Provides rail-to-rail signal switching capability for analog signals
- Features high bandwidth and fast switching speeds for signal integrity
- Includes ESD protection rated at 4kV HBM
Applications
- Portable equipment requiring low-power signal routing
- Battery-powered systems utilizing low-voltage logic control
- Audio and video signal path switching applications
Procurement Notes
Verify the specific ordering suffix 'TA' corresponds to the SOT23-5 package configuration as defined in the manufacturer's documentation. Confirm that the 'E' suffix indicates lead-free and halogen-free compliance requirements. Ensure the 'X' suffix matches the required tape and reel packaging format for automated assembly processes.
Selection Notes
Select this component when a single-channel SPST switch is required for low-voltage digital or analog signals. Consider the maximum on-resistance specifications across the intended operating voltage range. Evaluate the package thermal dissipation limits against the expected load current to ensure reliable operation within the specified temperature range.
Part Context
This part belongs to the PI5A3166 family of low-voltage analog switches. The TA suffix specifically denotes the SOT23-5 plastic package variant, distinguishing it from the SC70-5 (CEX) package option. The device shares identical electrical characteristics with other package variants within the same product line.
Replacement Considerations
The PI5A3166CEX serves as a direct functional replacement with an identical pinout and electrical specification, differing only in the SC70-5 package form factor.
FAQ
What is the maximum DC output current rating?
The maximum DC output current is rated at 128mA.
How does the on-resistance vary with supply voltage?
On-resistance increases as the supply voltage decreases; it is typically 1.2Ω at 4.5V and up to 1.9Ω at 1.65V under specific load conditions.
Is the input logic compatible with standard CMOS levels?
Yes, the logic input thresholds are defined relative to VCC, ensuring compatibility with standard CMOS logic levels across the 1.65V to 5.5V range.
