Overview
The SN74LVC1G3157DTBR is a single-channel, single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 5.5V and supports bidirectional signal transmission up to VCC. The device features a maximum on-resistance of 15 ohms and a -3dB bandwidth of 340MHz. Switching times are specified with a maximum Ton of 5.7ns and Toff of 3.8ns. It is housed in a compact 6-X2SON package measuring 0.8mm by 1mm. The component functions across an extended temperature range from -40°C to 125°C.
Feature Summary
- Supports rail-to-rail signal processing for both analog and digital signals
- Provides high linearity with low charge injection characteristics
- Includes robust electrostatic discharge protection exceeding JESD standards
Applications
- Signal gating and chopping circuits
- Modulation and demodulation in modem applications
- Signal multiplexing for ADC and DAC systems
Procurement Notes
Verify the specific suffix DTBR corresponds to the X2SON package and tape-and-reel configuration. Confirm the operating temperature range matches the design requirement of -40°C to 125°C. Ensure ESD protection levels meet the target application's environmental stress specifications before finalizing procurement.
Selection Notes
Select this component when a small footprint is required alongside high-speed switching capabilities. The 15-ohm on-resistance suits general-purpose routing where minimal signal distortion is critical. Verify that the 340MHz bandwidth aligns with the highest frequency components present in the signal path.
Part Context
This part belongs to the SN74LVC1G3157 family of SPDT analog switches. It shares core electrical specifications with variants like the DBVR and DSFR but differs in physical packaging. The DTBR specifically utilizes the 6-X2SON form factor, offering a smaller profile compared to SOT-23 or SC-70 alternatives.
Replacement Considerations
SN74LVC1G3157DBVR offers identical electrical performance in a SOT-23-6 package. SN74LVC1G3157DSFR provides the same functionality in a 6-SON(1x1) package. Substitution requires verifying pinout compatibility and thermal dissipation requirements for the alternative package type.
