Overview
The PI5A3157CEX is a single-pole double-throw (SPDT) analog switch manufactured by Diodes Incorporated in a 6-pin SOT-363 package. It operates on a supply voltage range of 1.65V to 5.5V with a maximum on-resistance of 12Ω at 1.65V, 9Ω at 2.3V, and 6Ω at 4.5V. The device features a high bandwidth of 250MHz, propagation delay of 1.2ns max at 2.3V, and turn-on/turn-off times up to 23ns max at 1.65V. It provides 57dB off-isolation and 54dB crosstalk rejection at 10MHz, functioning within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Break-before-make switching prevents simultaneous switch activation to eliminate signal disruption during transitions.
- Control input tolerates drive signals up to 5.5V independent of the supply voltage.
- Rail-to-rail signal range accommodates wide operating power supply voltages from 1.65V to 5.5V.
Applications
- Cell Phones
- PDAs
- Portable Instrumentation
- Battery Powered Communications
- Computer Peripherals
Procurement Notes
Verify the component against the official datasheet DS41486 Rev 2-2 to confirm authenticity. Ensure the ordering suffix matches the required packaging configuration. Confirm compliance with RoHS 3 directives and verify that the device meets the specific environmental requirements for your intended application before finalizing procurement.
Selection Notes
Select this component when a low-voltage SPDT switch with rail-to-rail signal handling is required. The break-before-make feature makes it suitable for applications needing uninterrupted signal paths during switching events. Verify that the maximum on-resistance at your target supply voltage aligns with your circuit's power dissipation constraints.
Part Context
This part belongs to the PI5A3157 series of CMOS analog switches designed for bus and analog applications. It serves as an improved direct replacement for the NC7SB3157. The device integrates high bandwidth and fast transition speeds into a compact surface-mount package suitable for portable electronic designs.
Replacement Considerations
The datasheet identifies the NC7SB3157 as a compatible predecessor. Verify pin compatibility and electrical parameter alignment before substitution.
FAQ
What is the maximum control input voltage tolerance?
The control input tolerates input drive signals up to 5.5V, independent of the supply voltage.
How does the device prevent signal disruption during switching?
It utilizes break-before-make switching logic, which ensures both switches are not enabled simultaneously.
What is the specified off-isolation performance?
The device provides a typical off-isolation of 57dB at 10MHz.
