Overview
The SN74CBT16212DL is a digital bus switch IC manufactured by Texas Instruments, belonging to the SN74CBT16212C series. It features a 20-bit FET bus switch architecture housed in an SSOP-48 package. Key electrical parameters include a maximum on-resistance of 12 Ohms and a maximum propagation delay of 250 ps. The device operates within a supply voltage range of 4 V to 5.5 V, with a maximum power supply current of 3 uA. It supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides 20-bit bidirectional data path switching capability for high-density bus applications.
- Utilizes FET technology to achieve low on-resistance and minimal signal distortion.
- Features low static power consumption suitable for energy-efficient system designs.
Applications
- High-speed data bus switching in computer and industrial control systems
- Signal routing in telecommunications equipment
- Memory bus expansion and configuration
Procurement Notes
Verify the specific suffix 'DL' against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the SSOP-48 package. Confirm RoHS compliance status through the latest component documentation before finalizing procurement orders.
Selection Notes
Select this component when a 20-bit wide bus switch is required with tight propagation delay constraints. The SSOP-48 package offers a compact solution for space-constrained designs. Verify that the 4V to 5.5V supply range aligns with the system's power rails and that the -40°C to +85°C temperature range meets environmental requirements.
Part Context
This part belongs to the SN74CBT16212C family of 20-bit FET bus switches from Texas Instruments. These devices are designed for high-speed data transfer applications requiring low insertion loss and fast switching speeds. The family shares common electrical characteristics but may vary in packaging options such as TSSOP or SSOP configurations.
Replacement Considerations
Consult the manufacturer's obsolescence notices and replacement guide for direct substitutes. Cross-reference pinouts and electrical specifications with alternative 20-bit bus switches if sourcing issues arise.
