SN74CBT16390DL

Overview

The SN74CBT16390DL is a dual 8-bit bus switch manufactured by Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes a 24-pin TSSOP package with surface-mount installation. The device supports bidirectional data transmission and features active low enable inputs for precise control. It is engineered to minimize signal distortion and crosstalk in high-speed digital systems.

Feature Summary

• Supports bidirectional data transmission between two buses
• Operates at low supply voltages from 1.65 V to 3.6 V
• Features active-low enable inputs for flexible system control

Applications

• Portable equipment requiring low power consumption
• High-speed data routing in consumer electronics
• Battery-powered devices needing efficient bus switching

Procurement Notes

Verify the specific suffix 'DL' corresponds to the 24-pin TSSOP package and tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance standards required for your manufacturing process. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require low on-resistance and minimal propagation delay for data bus isolation. It is suitable for applications where space constraints necessitate a compact TSSOP package. Consider its low standby current capabilities for battery-operated systems requiring extended operational life without frequent recharging.

Part Context

This part belongs to the SN74CBT family of bus switches, which are optimized for low-voltage operation. Unlike standard logic gates, these switches provide transparent data paths controlled by external signals. The family is widely used in modern digital interfaces to manage data flow efficiently while maintaining signal integrity across various voltage domains.

Replacement Considerations

Check for equivalents such as the SN74CBT16390DGGR or other variants within the same CBT series that offer compatible pinouts and electrical characteristics. Ensure any substitute maintains the same voltage range and package dimensions to fit existing PCB layouts without modification.
