SN74CBTLV3253PWR

Overview

The SN74CBTLV3253PWR is a dual 1-of-4 multiplexer/demultiplexer switch IC from Texas Instruments, housed in a TSSOP-16 package. It operates within a supply voltage range of 2.3 V to 3.6 V. The device features a maximum on-resistance of 40 Ohms, ensuring signal integrity across applications. Propagation delays are specified with a maximum run time of 6.7 ns and a maximum isolation time of 6.1 ns. It supports a bandwidth of 200 MHz and functions reliably between -40°C and +85°C.

Feature Summary

• Dual-channel architecture providing two independent 1-of-4 multiplexing paths for efficient signal routing.
• Low-voltage operation optimized for modern low-power digital systems requiring 2.3 V to 3.6 V power supplies.
• High-speed switching capabilities characterized by low propagation delay and high bandwidth performance.

Applications

• Portable consumer electronics requiring compact signal routing solutions
• Industrial control systems utilizing low-voltage logic interfaces
• Telecommunications equipment managing data bus signals

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference pinout diagrams with target PCB layout requirements to prevent installation errors.

Selection Notes

Select this component when a dual-channel 1-of-4 configuration is required within a limited footprint. The TSSOP-16 package offers a balance between pin count and board space efficiency. Consider the 2.3 V minimum operating voltage to ensure compatibility with the system's power rail. Evaluate the 40 Ohm on-resistance against signal loss tolerances in the intended application path.

Part Context

This part belongs to the SN74CBTLV3253 series of low-voltage multiplexer switches. It serves as a specialized solution for routing multiple input lines to a single output or vice versa. The series is designed to replace mechanical relays in solid-state applications, offering faster switching speeds and longer operational lifespans compared to electromechanical alternatives.

Replacement Considerations

Check for SN74CBTLV3253RGYR as an alternative package option within the same functional family. Verify pin-to-pin compatibility before substituting with other CBTLV series devices. Ensure voltage levels and package dimensions match the existing design constraints.
