SN74CBT16233DGVR

Overview

The SN74CBT16233DGVR is a digital bus switch IC from Texas Instruments, featuring 16-bit 1-of-2 FET configuration. It operates within a supply voltage range of 4V to 5.5V, with a maximum operating voltage of 5V. The device exhibits a maximum on-resistance of 7 ohms and functions reliably across an extended temperature range from -40°C to +85°C. Packaged in a 56-pin TVSOP format for surface mount installation, it supports RoHS compliance standards.

Feature Summary

• Provides 16-bit bidirectional data switching capability via FET technology
• Supports 1-of-2 multiplexing configuration for signal routing
• Ensures low on-resistance for minimal signal attenuation
• Compatible with standard surface mount assembly processes

Applications

• High-speed digital bus switching applications
• Data line isolation and protection circuits
• Signal routing in multi-voltage domain systems

Procurement Notes

Verify the specific package variant and tape-and-reel specifications against the official datasheet before ordering. Confirm that the 56-pin TVSOP footprint matches your PCB layout requirements. Ensure the operating voltage range aligns with your system's power supply rails to maintain reliable performance within the specified temperature limits.

Selection Notes

Select this component when a high-density 16-bit bus switch is required for 5V logic systems. The TVSOP-56 package offers a compact solution for space-constrained designs. Consider the 7-ohm on-resistance specification for signal integrity requirements. Verify compatibility with existing control logic levels for the 1-of-2 selection inputs.

Part Context

This part belongs to the SN74CBT16 series of bus switches designed for high-speed data transmission. It complements other Texas Instruments logic families by providing robust switching capabilities for parallel data lines. The device integrates multiple independent switches into a single package to reduce board space and simplify design complexity.

Replacement Considerations

Consult the manufacturer's cross-reference guide for direct pin-compatible alternatives. Verify electrical parameters such as on-resistance and propagation delay when substituting with similar bus switch ICs from other manufacturers.
