Overview
The SN74LVC1G3157YZTR is a single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments, belonging to the SN74LVC1G3157 series. It utilizes advanced CMOS technology and operates on a single power supply ranging from 1.65V to 5.5V. The device supports bidirectional signal transmission with rail-to-rail capability, handling both analog and digital signals up to VCC peak. Key electrical characteristics include a maximum on-resistance of 15Ω, a typical propagation delay of 0.5ns at 3V, and a -3dB bandwidth of 340MHz. It features low off-state leakage current of 1µA and high ESD protection ratings. The component is housed in a compact 6-X2SON package measuring 0.8mm x 1mm, designed for surface-mount installation.
Feature Summary
- Supports bidirectional signal routing with rail-to-rail voltage handling for both analog and digital applications
- Provides high-speed switching performance with low propagation delay and wide bandwidth
- Features low on-resistance and minimal off-state leakage to preserve signal integrity
- Includes robust electrostatic discharge and latch-up protection for reliable operation
Applications
- Portable consumer electronics requiring space-efficient signal routing
- Computer peripherals and data acquisition systems
- Communication networks and signal processing circuits
- Audio equipment and signal modulation/demodulation interfaces
Procurement Notes
Verify the specific suffix YZTR corresponds to the 6-X2SON package and tape-and-reel packaging configuration. Confirm that the ordering part number matches the exact pinout and electrical specifications required for the target design. Ensure compliance with RoHS directives and check for any recent product change notices affecting assembly or material composition before finalizing procurement.
Selection Notes
Select this component when a single-channel SPDT switch is needed within a 1.65V to 5.5V supply range. It is suitable for designs prioritizing small footprint due to the X2SON package. Consider its 15Ω max on-resistance and 340MHz bandwidth for high-frequency signal paths. Verify that the operating temperature range meets the environmental requirements of the end application.
Part Context
This device is part of the SN74LVC1G3157 family of single-pole double-throw analog switches from Texas Instruments. The family shares core logical functions but varies in package options such as SC-70, SOT-23, and X2SON. The YZTR suffix specifically denotes the X2SON package variant with reel packaging, distinguishing it from other physical form factors in the same functional series.
Replacement Considerations
Direct substitutes include other SN74LVC1G3157 variants with different packages, such as SN74LVC1G3157DCKR (SC-70) or SN74LVC1G3157DBVR (SOT-23), provided the PCB layout accommodates the package difference. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
