Overview
The SN74LVC1G66DSFR is a single bilateral analog switch manufactured by Texas Instruments, belonging to the SN74LVC1G66 series. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and supports bidirectional signal transmission with amplitudes up to 5.5 V peak. The device features a maximum on-resistance of 10 Ohms and offers fast switching speeds, with a maximum turn-on time of 4.2 ns and a maximum turn-off time of 5 ns. It is housed in a compact 6-XFDFN package (also designated as 6-SON) and functions within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Supports bidirectional transmission of both analog and digital signals across the full operating voltage range.
- Provides low on-resistance for efficient signal routing in portable and battery-powered applications.
- Features high ESD protection performance compliant with JESD22 standards.
Applications
- Wireless devices requiring signal gating or modulation
- Audio and video signal routing systems
- Portable computing equipment
- Wearable electronic devices
Procurement Notes
Verify the specific suffix DSFR corresponds to the 6-XFDFN/6-SON surface-mount package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component when a single SPST analog switch is needed for low-voltage logic interfacing. The LVC technology ensures compatibility with 1.65V to 5.5V systems. Consider the small footprint and low power consumption for space-constrained designs. Verify that the 10 Ohm on-resistance meets the signal integrity requirements of the specific circuit path.
Part Context
This part belongs to the Texas Instruments SN74LVC1Gxx family of ultra-small single-channel analog switches. These devices are designed for portable electronics where minimal board space and low power consumption are critical. The LVC (Low Voltage CMOS) technology allows operation down to 1.65V while maintaining robust performance at higher voltages up to 5.5V.
Replacement Considerations
SN74LVC1G66DBVR: Single channel analog switch in SOT-23-5 package. SN74LVC1G66DRLR: Single channel analog switch in SOT-5X3-5 package. Both variants share identical electrical characteristics but differ in physical footprint and pinout compatibility.
