Overview
The SN74CBT1G384DCKT is a single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features an on-resistance of 10 ohms at VCC = 3.3 V. The device supports bidirectional data transfer with low charge injection of 0.2 pC and offers a bandwidth exceeding 1 GHz. It is housed in a SC-70-5 package and functions across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Supports bidirectional data transfer for signal routing applications
- Features ultra-low on-resistance for minimal signal attenuation
- Provides high bandwidth suitable for RF and video signals
- Operates with low power consumption and fast switching speeds
Applications
- Portable equipment requiring signal path switching
- Video and audio signal routing systems
- RF signal switching circuits
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'DCKT' corresponds to the SC-70-5 package and tape-and-reel quantity. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating voltage aligns with the 1.65 V to 5.5 V specification. Check for any recent production change notices affecting pinout or electrical characteristics.
Selection Notes
Select this component when a single SPDT switch is required for low-voltage digital or analog signals. Compare against the SN74CBT1G3157 if differential signaling or multiplexing is needed instead of simple switching. Consider the SC-70-5 package size constraints relative to available PCB real estate. Evaluate the 10-ohm on-resistance against your signal integrity requirements.
Part Context
This part belongs to the Texas Instruments SN74CBT1G series of single analog switches. It complements other logic families like LVC and AHC but is optimized for analog signal transmission rather than digital logic processing. The series provides solutions for compact board designs requiring efficient signal routing between multiple sources or destinations.
Replacement Considerations
The SN74CBT1G384DCKR is a compatible alternative with identical electrical specifications but differs in packaging format. Verify that the lead frame material and thermal performance meet your design requirements before substituting.
