DS26C32AME/883

Overview

The DS26C32AME/883 is a quad differential line receiver manufactured by Texas Instruments, designed for balanced and unbalanced digital data transmission. It meets RS-422, RS-423, and Federal Standards 1020 and 1030. The device operates with a supply voltage range of 4.5V to 5.5V and functions within an operating temperature range of -55°C to +125°C. It features CMOS design for low power consumption and includes internal pull-up and pull-down resistors to prevent output oscillation on unused channels. The component provides TRI-STATE outputs with 6mA source and sink capability.

Feature Summary

• CMOS design architecture optimized for low power consumption while maintaining performance standards.
• Integrated input fail-safe circuitry ensures stable operation under specific input conditions.
• TRI-STATE outputs facilitate direct connection to system buses without loading issues.
• Inputs do not load the line when VCC is at 0V, supporting hot-swap scenarios.

Applications

• Balanced digital data transmission systems compliant with RS-422 standards.
• Unbalanced digital data transmission applications adhering to RS-423 protocols.
• Systems requiring compliance with Federal Standards 1020 and 1030.
• Bus-organized systems utilizing TRI-STATE output connections.

Procurement Notes

Verify that the ordering suffix matches the required package type, as the DS26C32A series includes multiple variants such as CDIP, LCCC, and CFP. Confirm the specific sub-group requirements for Mil-Std-883 quality conformance inspection if applicable to the end-use environment. Ensure compatibility with existing board layouts for the selected package option before finalizing procurement orders.

Selection Notes

Select this component when high reliability and wide temperature operation are required for differential line reception. The device is pin-compatible with the DS26LS32A and AM26LS32, allowing for potential drop-in replacements in existing designs. Consider the specific package availability, as different suffixes correspond to distinct physical footprints like LCCC or CDIP. Evaluate the need for TRI-STATE bus connectivity and fail-safe input characteristics during the design phase.
