Overview
The NC7SB3157L6X is a single-channel, low-voltage SPDT analog switch manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V and is housed in a 6-pin MicroPak package. The device features a maximum on-resistance of 15 Ohms and supports a -3dB bandwidth of 250 MHz. Switching times are specified with a maximum turn-on time of 5.2 ns and a maximum turn-off time of 3.5 ns. It functions as a 2:1 multiplexer or demultiplexer bus switch with an operating temperature range from -40°C to +85°C.
Feature Summary
- Supports low-voltage operation suitable for portable applications
- Provides high-speed signal switching capabilities
- Offers compact surface-mount packaging for space-constrained designs
Applications
- Portable equipment signal routing
- Cellular phones and handheld devices
- LCD video switches
- Video and audio signal switching
Procurement Notes
Verify the specific suffix L6X against the manufacturer's current datasheet to confirm the MicroPak W package configuration. Ensure that the ordering information matches the required tape and reel quantities. Cross-reference the RoHS compliance status and moisture sensitivity level with the latest environmental declarations before finalizing procurement orders.
Selection Notes
Select this component when a single-pole double-throw switch is required for low-voltage digital or analog signals. The 15 Ohm on-resistance and 250 MHz bandwidth make it suitable for general-purpose signal path management. Consider the 6-pin MicroPak footprint during PCB layout to ensure adequate clearance and thermal performance within the specified operating temperature range.
Part Context
This part belongs to the NC7SB3157 series of low-voltage analog switches. The series includes variants with different packaging options such as SC-70-6 and MicroPak. These components are designed for battery-powered applications requiring minimal power consumption and small form factors while maintaining signal integrity across various data rates.
Replacement Considerations
Direct replacements include other NC7SB3157 variants with compatible pinouts, such as NC7SB3157P6X, provided the package type difference between MicroPak and SC-70 is acceptable for the design.
