SN75110AD Equivalent & Substitute Parts

Part Overview

The SN75110AD is a 2/0 Driver IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is classified as obsolete, indicating it has been discontinued and is no longer in active production. The SN75110AD operates within a supply voltage range of 4.75V to 5.25V and is rated for operating temperatures from 0°C to 70°C. Due to its obsolete status, identifying functionally compatible substitute components is essential for ongoing system maintenance, redesign efforts, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75110AD is determined by the following critical parameters:

• Driver/Receiver Configuration: The SN75110AD provides 2 drivers and 0 receivers. Substitute components must support equivalent or enhanced driver/receiver functionality.
• Supply Voltage Compatibility: The operating voltage range of 4.75V to 5.25V establishes the baseline requirement. Substitute parts must support overlapping or broader voltage ranges.
• Package and Mounting: Surface mount technology in SOIC format is required for direct board-level compatibility.
• Compliance and Certifications: RoHS3 compliance and MSL rating ensure environmental and handling compatibility.
• Product Status: Active production status of substitute components ensures long-term availability and supply chain reliability.

The SN65C1167ENSR is identified as a manufacturer-recommended substitute. While it provides enhanced functionality (2/2 transceiver configuration with RS422/RS485 protocol support) compared to the driver-only architecture of the SN75110AD, it maintains compatibility through overlapping electrical specifications and surface mount packaging.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR is the manufacturer-recommended substitute for the obsolete SN75110AD. Both components are manufactured by Texas Instruments and maintain ROHS3 compliance with MSL rating of 1 (Unlimited), ensuring equivalent environmental and handling standards.

The SN65C1167ENSR provides active product status, guaranteeing continued availability and supply chain support. The supply voltage range of 4.5V to 5.5V encompasses the SN75110AD specification of 4.75V to 5.25V, ensuring electrical compatibility within the original operating envelope. The extended operating temperature range of -40°C to 85°C exceeds the SN75110AD specification of 0°C to 70°C, providing broader thermal performance.

The SN65C1167ENSR operates in a 16-SOIC package compared to the 14-SOIC package of the SN75110AD. This package difference requires PCB layout evaluation to confirm physical compatibility. The transceiver architecture (2/2 configuration with RS422/RS485 protocol support) provides enhanced functionality beyond the driver-only configuration of the SN75110AD, offering additional design flexibility for interface applications.

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the SN75110AD without circuit modifications?

A: The SN65C1167ENSR provides compatible electrical specifications within the SN75110AD operating envelope. However, the package size difference (16-SOIC versus 14-SOIC) requires PCB layout verification. The enhanced transceiver functionality does not preclude use in driver-only applications, but pin configuration and signal routing must be evaluated for your specific circuit design.

Q: What is the significance of the driver/receiver configuration difference (2/0 versus 2/2)?

A: The SN75110AD provides 2 drivers with no receiver capability. The SN65C1167ENSR provides 2 drivers and 2 receivers, enabling full-duplex communication. In applications requiring driver-only functionality, the receiver channels of the SN65C1167ENSR remain available but unused, presenting no operational conflict.

Q: Are there compliance or certification concerns when substituting these components?

A: Both components maintain identical RoHS3 compliance and MSL rating of 1 (Unlimited). No compliance degradation occurs with substitution. The SN65C1167ENSR active product status ensures continued compliance certification and supply chain support.

Q: How does the package size difference affect board-level integration?

A: The SN65C1167ENSR 16-SOIC package (0.209", 5.30mm width) is larger than the SN75110AD 14-SOIC package (0.154", 3.90mm width). PCB footprint compatibility must be confirmed. If the original PCB layout cannot accommodate the larger package, alternative component placement or PCB redesign may be required.

Q: What is the supply voltage compatibility between these components?

A: The SN75110AD operates at 4.75V to 5.25V. The SN65C1167ENSR operates at 4.5V to 5.5V. The SN65C1167ENSR range is broader and fully encompasses the SN75110AD specification, ensuring electrical compatibility across the original operating voltage envelope.
