Overview
The QS4A205QG8 is a multiplexer/demultiplexer IC from the Renesas QS4A205 series, featuring four SPDT switch circuits configured as two 2:1 MUX-DEMUX channels. It operates within a single 5V supply voltage range of 4.75 V to 5.25 V. The device provides an on-resistance maximum of 17 Ohms and supports a -3dB bandwidth of 830 MHz. Switching times are limited to 6 ns for both turn-on and turn-off durations. It is housed in a 16-QSOP surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates four single-pole double-throw (SPDT) analog switches into a compact integrated circuit.
- Supports high-frequency signal routing with a bandwidth capability up to 830 MHz.
- Features low on-resistance to minimize signal attenuation during conduction.
- Provides fast switching transitions suitable for time-sensitive data routing applications.
Applications
- Signal routing in communication equipment requiring multiplexing capabilities
- Data acquisition systems utilizing analog signal selection
- Test and measurement instruments needing precise signal path control
Procurement Notes
Verify the specific suffix 'Q8' against official Renesas documentation to confirm tape-and-reel packaging versus tube configuration. Ensure the component meets RoHS3 compliance requirements for your manufacturing process. Cross-reference the manufacturer part number IDTQS4A205QG8 for accurate sourcing history and availability status.
Selection Notes
Select this component when a 2:1 multiplexer configuration is required rather than a standard 4:1 layout. The 16-QSOP package offers a balance between pin count and board space. Consider the 17 Ohm on-resistance limit for signal integrity requirements in low-voltage analog paths.
Part Context
This part belongs to the QS4A205 family of analog switches manufactured by Renesas Electronics Corporation. The family includes variants such as the QS4A205 and QS4A105, which differ in channel count and package options. The QS4A205 specifically focuses on providing dual 2:1 multiplexing functionality within a single chip.
Replacement Considerations
Publicly listed substitutes include ADG774BRQZ from Analog Devices and FSAL200MTCX from onsemi. Verify pin compatibility and electrical specifications before substitution.
FAQ
What is the maximum operating voltage for the QS4A205QG8?
The device is designed to operate with a single power supply voltage ranging from 4.75 V to 5.25 V.
Does the QS4A205QG8 support differential signaling?
No, the QS4A205QG8 consists of single-ended SPDT switches and does not natively support differential signaling configurations.
What is the typical off-state isolation performance?
The typical off-state isolation is specified at -60 dB, ensuring effective signal blocking when the switch is open.
