Overview
The QS4A101QG8 is a high-performance CMOS analog switch featuring four independent single-pole single-throw (SPST) channels. It operates on a single 5V supply and provides a maximum on-resistance of 17 ohms with a -3dB bandwidth of 1.4GHz. The device supports bidirectional signal flow and includes TTL-compatible control inputs. Key electrical specifications include a maximum charge injection of 1.5pC, off-current leakage of 1nA, and a crosstalk performance of -75dB at 30MHz. Switching times are specified at 6.5ns for turn-on and 6ns for turn-off. It is housed in a 16-QSOP surface-mount package and functions within an operating temperature range of -40°C to +85°C.

Procurement Notes
Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix 'Q' indicates RoHS compliance and lead-free status as per manufacturer standards. Check for End-of-Life notices, as this part may be discontinued. Request official datasheets and test reports to ensure technical parameters match system requirements before integration.
Selection Notes
Select this component when designing circuits requiring low distortion and high bandwidth for analog signal paths. Ensure the single 5V supply voltage aligns with the system power architecture. Consider the 16-QSOP package dimensions for PCB layout constraints. Verify that the 17-ohm on-resistance meets the signal integrity requirements for the specific application load.
Part Context
The QS4A101QG8 belongs to the QS4A101 family of analog switches manufactured by Renesas Electronics Corporation. This series is designed for general-purpose high-speed switching applications. The 'QG8' suffix typically denotes specific packaging and environmental compliance variations within the broader product line. It serves as a discrete solution for signal multiplexing and demultiplexing tasks.
Replacement Considerations
Public records indicate the QS4A101QG8 has reached End-of-Life status. Designers should evaluate alternative components from the same manufacturer or compatible third-party analog switches. Ensure any replacement maintains equivalent bandwidth, on-resistance, and package footprint to minimize redesign efforts.
