SN75ALS057N

The SN75ALS057N from Texas Instruments is a quad transceiver IC, part of the Advanced Low-Power Schottky (ALS) family. It is designed for high-speed data communication in backplane applications and is suitable for IEEE Standard 896 applications.

This transceiver features four channels with independent driver-input and receiver-output pins. It operates over a temperature range of 0°C to 70°C and requires an operating voltage between 4.75V and 5.25V. The device boasts low power dissipation of 52.5 mW/Channel maximum and a logic-level 1-V bus swing to reduce power consumption.

The SN75ALS057N utilizes open-collector driver outputs with series Schottky diodes to minimize capacitive loading on the bus. The driver outputs generate trapezoidal waveforms, which help reduce noise coupling between adjacent channels. The drivers are capable of handling an equivalent DC load as low as 18.5 Ω. Receivers are equipped with internal low-pass filters for enhanced noise immunity.

Packaged in a 20-PDIP through-hole configuration, the SN75ALS057N is designed for easy integration into existing circuit boards. Its features make it a functional equivalent to National Semiconductor's DS3896 and DS3897, offering a faster, lower-power alternative.
