Overview
The SN74CBT16232DLR is a synchronous 16-bit 1-of-2 FET multiplexer/demultiplexer from Texas Instruments. It operates with a supply voltage range of 2.7 V to 5.5 V and features an on-resistance of 14 ohms maximum. The device supports a bandwidth of 200 MHz and handles continuous input/output current up to 128 mA. It is housed in a 56-pin SSOP (DL) package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Synchronous 16-bit data path switching capability
- Low on-resistance for minimal signal attenuation
- Wide supply voltage compatibility
- High-speed bandwidth performance
Applications
- Data bus switching applications
- Multiplexing and demultiplexing signals
- Portable equipment requiring low power consumption
Procurement Notes
Verify the complete part number including the suffix 'DLR' to ensure correct packaging and tape-and-reel configuration. Confirm that the 56-pin SSOP footprint matches your PCB design. Check the specific revision level against your system requirements to ensure compatibility with existing firmware or hardware interfaces.
Selection Notes
Select this component when a synchronous 16-bit switch is required for high-density data routing. Ensure the 56-pin SSOP package fits the available board space. Verify that the 2.7V to 5.5V operating range aligns with the system's power supply rails and that the 14-ohm on-resistance meets the signal integrity requirements of the connected lines.
Part Context
This device belongs to the Texas Instruments Widebus family, designed for efficient management of multiple data paths. It integrates 16 independent switches into a single package, reducing component count compared to discrete solutions. The synchronous control allows for precise timing alignment in complex digital systems.
Replacement Considerations
Check for direct pin-compatible alternatives within the same Widebus family. Verify that any substitute maintains the 56-pin SSOP package and synchronous operation mode. Ensure electrical parameters such as on-resistance and supply voltage range are equivalent or superior.
