DS26C32ATM

Overview

The DS26C32ATM 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 supports an operating temperature range of -40°C to +85°C. It features typical propagation delays of 19 ns and input hysteresis of 60 mV. The CMOS design ensures low power consumption while maintaining high sensitivity over a ±7V common-mode voltage range.

Feature Summary

• CMOS architecture providing low power consumption
• High sensitivity with ±0.2V threshold over a wide common-mode voltage range
• TRI-STATE outputs compatible with system buses
• Internal pull-up and pull-down resistors prevent output oscillation on unused channels

Applications

• Balanced digital data transmission systems
• Unbalanced digital data transmission systems
• RS-422 interface circuits
• Federal Standards 1020 and 1030 compliant applications

Procurement Notes

Verify the specific ordering suffix to confirm package type and lead finish. Confirm RoHS compliance status as some variants may differ. Check current production status, as certain suffixes indicate lifetime buy or obsolete status. Ensure the selected variant matches the required operating temperature range for the intended application environment.

Selection Notes

Select the DS26C32ATM when a quad differential receiver meeting RS-422 standards is required. Choose this part for designs needing TRI-STATE outputs and internal biasing for unused receivers. Verify that the SOIC-16 package fits the PCB layout constraints. Ensure the system operates within the specified 4.5V to 5.5V supply voltage limits.

Part Context

The DS26C32A series includes variants like the DS26C32AM for extended temperature ranges. The 'AT' suffix denotes the commercial temperature grade (-40°C to +85°C). The 'M' suffix indicates the SOIC surface-mount package. This component is pin-compatible with the DS26LS32A and AM26LS32, facilitating direct upgrades in existing designs.

Replacement Considerations

The DS26C32AM serves as a replacement for extended temperature requirements. The DS26LS32A and AM26LS32 are pin-compatible alternatives. Verify electrical characteristics match before substitution.
