PI5A3157BC6EX

Overview

The PI5A3157BC6EX is a low voltage single-pole double-throw (SPDT) analog switch manufactured by Diodes Incorporated. It functions as a 2:1 multiplexer or demultiplexer bus switch housed in a 6-pin SOT-363 (SC-70) surface-mount package. The device operates within a supply voltage range of 1.65V to 5.5V and supports an ambient operating temperature from -40°C to +85°C. Key electrical specifications include a maximum on-resistance of 11 ohms at VCC=4.5V, a typical propagation delay of 0.9ns at 3.0V, and a -3dB bandwidth of 350MHz. The component features low off-state leakage current and high isolation characteristics suitable for signal routing applications.

Feature Summary

• Supports bidirectional signal transmission with a single SPDT switching configuration
• Operates across a wide low-voltage power supply range from 1.65V to 5.5V
• Provides high-speed data routing with low propagation delay and high bandwidth
• Ensures signal integrity through low charge injection and high off-isolation

Applications

• Portable equipment requiring low voltage signal switching
• Cellular phones and handheld devices
• LCD and VGA display modules
• Video compression and decompression circuits
• Memory card interfaces

Procurement Notes

Verify the specific ordering suffix 'C6' against the manufacturer's official documentation to confirm the SC-70 package type. Ensure compliance with RoHS 3 directives and lead-free requirements specified in the datasheet. Confirm that the component status remains active, as the C6 package may be marked as not recommended for new designs in some contexts. Validate all electrical parameters against the intended operating conditions before finalizing procurement.

Selection Notes

Select this component when a compact SPDT analog switch is required for low-voltage digital or analog signal routing. The PI5A3157BC6EX is suitable for applications demanding minimal signal distortion and fast switching speeds. Consider the 11-ohm maximum on-resistance and 350MHz bandwidth when designing for high-frequency signals. Ensure the control logic levels align with the VIH and VIL specifications provided in the DC electrical characteristics table for reliable operation.

Part Context

The PI5A3157B series represents a family of low voltage SPDT analog switches designed by Diodes Incorporated. This specific part utilizes the BC6 suffix to denote the 6-pin SOT-363 (SC-70) package variant. The series is engineered for portable electronics where space constraints and low power consumption are critical. Other variants in the family may offer different packaging options such as X1DFN, but share the same core switching functionality and electrical performance profiles.

Replacement Considerations

The datasheet lists the PI5A3157BXDBEX as an alternative package option within the same product family. Verify pin compatibility and electrical specifications when substituting between package types. No other cross-manufacturer replacements are confirmed in the provided documentation.
