SN75ALS053FN

Drivers, Receivers, Transceivers Overview

The SN75ALS053FN is a low-power Schottky (ALS) line transceiver manufactured by Texas Instruments. It integrates four drivers and four receivers in a single package, supporting RS-422 and RS-485 communication standards. The device operates with a supply voltage range of 4.75 V to 5.25 V and features TTL-compatible input levels. It utilizes a 32-WFQFN exposed pad package for surface-mount applications.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four differential drivers and four receivers for multi-drop bus communication
• Supports RS-422 and RS-485 data transmission protocols
• Features low-power Schottky technology for reduced current consumption
• Provides TTL-compatible logic input levels

Drivers, Receivers, Transceivers Applications

• RS-485 multi-drop communication networks
• RS-422 point-to-point or multi-point serial interfaces
• Industrial control system data buses
• Building automation and security systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant upon ordering, as sources indicate both bulk packaging and 32-WFQFN configurations. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the selected part number matches the required pinout and thermal pad specifications for your PCB layout design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring four-channel differential signaling in a compact footprint. Consider the ALS series characteristics for applications needing lower power dissipation compared to standard LS logic. Verify that the operating temperature range meets your environmental requirements and that the 5V supply rail is stable.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SN75ALS family of high-speed, low-power line transceivers. It is functionally similar to the SN75176 but offers integrated quad channel capability. The ALS technology provides improved speed and power efficiency over older bipolar implementations, making it suitable for modern embedded communication interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the SN75ALS series. Verify if the SN75ALS176ADR serves as a functional substitute for single-channel needs, though channel count differs. Confirm package compatibility before substituting with other manufacturers' equivalents.
