Overview
The SN74CBT3306CPWRE4 is a dual bus switch manufactured by Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 1.65 V to 3.6 V and supports bidirectional data transmission across two independent channels. The device utilizes FET technology to achieve low on-resistance and high bandwidth, making it suitable for high-speed signal routing. It is housed in an 8-pin TSSOP package and functions reliably within an operating temperature range of -40°C to +85°C.
Feature Summary
- Supports bidirectional data transmission with independent control for each channel
- Features low on-resistance for minimal signal attenuation
- Operates at low supply voltages down to 1.65 V
Applications
- Portable equipment requiring low power consumption
- High-speed data routing in consumer electronics
- Battery-powered systems utilizing low-voltage logic
Procurement Notes
Verify the specific suffix 'E4' indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the 'C' designation corresponds to the commercial temperature grade (-40°C to +85°C). Ensure the TSSOP-8 package dimensions match the target PCB footprint requirements before finalizing procurement specifications.
Selection Notes
Select this component when designing circuits that require switching between 1.65 V and 3.6 V logic levels with low insertion loss. It is appropriate for applications needing compact packaging and independent channel control. Compare against other CBT series variants if higher channel counts or different voltage tolerances are required for the specific system architecture.
Part Context
This part belongs to the Texas Instruments SN74CBT3306 family of digital bus switches. These devices are engineered for low-voltage operation and offer high bandwidth performance. The family provides solutions for managing signal paths in space-constrained designs, maintaining signal integrity across various low-power electronic interfaces.
Replacement Considerations
Check for SN74CBT3306DWR or SN74CBT3306PWR as potential pin-compatible alternatives from the same manufacturer. Verify electrical parameters and package compatibility before substitution.
