Overview
The DS34C86TN/NOPB is a quad CMOS differential line receiver manufactured by Texas Instruments. It meets RS-422, RS-423, and Federal Standards 1020/1030 for balanced and unbalanced digital data transmission. The device operates with a supply voltage range of 4.5V to 5.5V and features an input sensitivity of ±0.2V over a common-mode voltage range of ±7V. Typical propagation delays are 19ns, with typical input hysteresis of 60mV. It includes TRI-STATE outputs with 6mA source/sink capability and separate enable pins for independent control.
Feature Summary
- CMOS design optimized for low power consumption while maintaining high-speed performance
- TRI-STATE outputs provide system bus compatibility with independent enable control
- Open input failsafe feature ensures output remains high when inputs are open
- 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 and RS-423 compliant communication interfaces
- Federal Standard 1020 and 1030 applications
Procurement Notes
Verify the exact package type and suffix against the official datasheet before ordering. Confirm RoHS compliance status and manufacturing lifecycle stage (Active or Obsolete) through authorized distributors. Ensure storage and handling procedures account for limited built-in ESD protection to prevent damage to MOS gates.
Selection Notes
Select this component for applications requiring quad differential reception with TRI-STATE bus compatibility. Verify that the required supply voltage falls within the 4.5V to 5.5V range. Consider the ±7V common-mode input range and ±0.2V sensitivity for signal integrity requirements in noisy environments.
Part Context
The DS34C86T series belongs to Texas Instruments' family of quad CMOS differential line receivers. It is pin-compatible with the DS3486 but offers improved low-power characteristics due to its CMOS construction. The device is designed to replace older TTL-based receivers in RS-422 and RS-423 applications.
Replacement Considerations
DS34C86TM/NOPB is a direct pin-compatible replacement offering Green/RoHS compliance. DS34C86TMX/NOPB provides the same functionality in tape-and-reel packaging for automated assembly.
