DS3883AVB

Overview

The DS3883AVB is a BTL (Balanced Transmission Line) 9-bit data transceiver manufactured by National Semiconductor. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of 0°C to 70°C (TA). The device features a 3-state output type with specified output currents of 2mA for high state and 24mA for low state. It is housed in a 44-QFP (10x10) surface mount package, providing a compact solution for balanced line interfacing applications requiring multi-bit data transmission capabilities.

Feature Summary

• Provides balanced transmission line interfacing capability through its BTL architecture
• Integrates nine bits of data transfer functionality within a single element
• Supports three-state output logic for effective bus management and isolation

Applications

• Balanced line data communication systems
• Industrial control interfaces requiring differential signaling
• Telecommunications equipment utilizing balanced transmission lines

Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are now part of Texas Instruments. Confirm the specific suffix 'AVB' matches the required temperature grade and package variant. Ensure compatibility with 5V logic levels and check for RoHS compliance status if environmental regulations apply to your deployment environment.

Selection Notes

Select this component when balanced transmission line driving is required for multi-bit data buses. The 9-bit width reduces component count compared to using multiple single-bit transceivers. Ensure the system design accommodates the 44-QFP footprint and that the 3-state outputs align with the bus topology requirements for the specific application interface.

Part Context

This device belongs to the DS3883A series of balanced line transceivers. It is designed to replace older discrete solutions for driving balanced loads. The series offers integrated protection and drive strength suitable for long-distance data transmission over twisted pair cables in noisy environments.

Replacement Considerations

Check for direct pin-compatible equivalents from Texas Instruments or other logic manufacturers offering 9-bit BTL transceivers in QFP packages. Verify electrical parameters such as output current and supply voltage ranges match exactly before substitution.
