Overview
The SN74CBTLV3857PWR is a low-voltage 10-bit FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V, with typical operation at 3.3 V. The device features a maximum on-resistance of 8 Ohms and a maximum propagation delay of 250 ps. It supports an operating temperature range from -40°C to +85°C and is housed in a TSSOP-20 package.
Feature Summary
- Integrates ten independent FET-based bus switches for high-density data routing
- Provides low on-resistance to minimize signal attenuation across the bus
- Ensures fast switching speeds suitable for high-frequency digital applications
Applications
- Portable consumer electronics requiring low power consumption
- Battery-powered systems utilizing low-voltage logic interfaces
- High-speed data bus isolation and switching circuits
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-20 tape-and-reel packaging configuration. Confirm that the 3.3 V nominal supply voltage aligns with the target system design requirements. Ensure compatibility with the specified industrial temperature range for the intended application environment.
Selection Notes
Select this component when a high-channel-count bus switch is required within a limited footprint. The 10-bit configuration reduces board space compared to multiple single-channel devices. The low-voltage operation makes it suitable for modern portable devices where power efficiency is critical.
Part Context
This part belongs to the SN74CBTLV3857 series of low-voltage bus switches. It shares functional similarities with other members of the CBTLV family but offers a specific 10-bit channel count. The device complements Texas Instruments' portfolio of signal switching solutions designed for mobile and embedded applications.
Replacement Considerations
Check for direct pin-compatible alternatives within the same series, such as the SN74CBTLV3857DW. Verify that any substitute maintains the same 10-bit architecture and low-voltage operational characteristics.
