Overview
The SN74CB3T16211DGVR is a digital bus switch manufactured by Texas Instruments, featuring a 12 x 1:1 circuit configuration within a single package. It operates on a single power supply ranging from 2.3V to 3.6V and supports an industrial operating temperature range of -40°C to +85°C. The component utilizes a 56-TFSOP (TSSOP) surface-mount package with a width of 6.10mm. This device is classified under the 74CB series and functions as a low-voltage FET bus switch designed for high-bandwidth signal routing applications.
Feature Summary
- Provides bidirectional data flow control through dedicated enable inputs for independent channel groups.
- Utilizes FET technology to achieve low on-resistance for minimal signal attenuation during transmission.
- Supports flexible voltage translation between different logic domains within the specified operating range.
Applications
- High-speed data bus switching in portable computing devices
- Signal routing in consumer electronics requiring low voltage operation
- Interface bridging between components operating at different logic levels
Procurement Notes
Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering part number matches the required package variant and moisture sensitivity level. Cross-reference the manufacturer's latest product change notifications to confirm current production status and any design revisions that may affect integration.
Selection Notes
Select this component when a 12-bit wide bus switch is required for 2.3V to 3.6V systems. Consider the 56-pin TSSOP footprint constraints during PCB layout. Evaluate the need for independent enable controls if separate management of data paths is necessary for the target application architecture.
Part Context
This device belongs to the Texas Instruments SN74CB3T16211 family of low-voltage FET bus switches. The DGVR suffix indicates a tape-and-reel packaging format suitable for automated assembly processes. The component is part of the broader 74CB series, which focuses on high-performance signal switching solutions for modern electronic systems.
Replacement Considerations
SN74CB3T16211DGGR is a verified parameter-equivalent alternative offering identical functionality in a reel package format. Verify pin-to-pin compatibility and electrical specifications before substitution.
