SN75ALS056N

Drivers, Receivers, Transceivers Overview

The SN75ALS056N is an octal transceiver from the SN75ALS056 series, manufactured by Texas Instruments. It utilizes Advanced Low-Power Schottky (ALS) circuitry and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports data transmission in densely populated backplanes with a maximum power dissipation of 52.5 mW per channel. It features open-collector driver outputs and internal low-pass filters for noise immunity. The component is characterized for operation between 0°C and +70°C and is housed in a 20-pin PDIP package.

Drivers, Receivers, Transceivers Feature Summary

• Generates trapezoidal bus output waveforms to reduce crosstalk between channels
• Open-collector driver outputs allow wired-OR connections on the bus
• Includes power-up and power-down protection to prevent glitching
• Receivers incorporate internal low-pass filters to improve noise immunity

Drivers, Receivers, Transceivers Applications

• Two-way data communication in densely populated backplanes
• IEEE Standard 896 applications
• High-speed advanced low-power Schottky interface circuits

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the through-hole PDIP-16 package configuration. Confirm that the required operating temperature range aligns with the 0°C to +70°C specification. Ensure the design accommodates the open-collector output requirements, including necessary pullup termination voltages for proper signal swing levels.

Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver is required for ALS-based high-speed backplane communication. Consider the SN75ALS057 if quad-channel functionality with independent driver inputs and receiver outputs is preferred. Verify that the system can support the 2-V pullup termination voltage needed to achieve the specified 1-V bus swing and minimize power consumption.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75ALS056/057 family of trapezoidal-waveform interface bus transceivers. It serves as a functional equivalent to National Semiconductor DS3896 and DS3897 devices, offering faster switching speeds and lower power dissipation characteristics suitable for legacy ALS logic families.
