DS96F175CJ Equivalent & Substitute Parts

Part Overview

The DS96F175CJ is a 0/4 Receiver RS422/RS485 interface IC manufactured by Texas Instruments in a 16-CDIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring compatible functionality.

The DS96F175CJ serves as a receiver in RS422 and RS485 communication systems, supporting data rates up to 15 Mbps with a receiver hysteresis of 50 mV. The part operates within a supply voltage range of 4.75V to 5.25V and is rated for 0°C to 70°C operating temperatures.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS96F175CJ is determined by the following critical parameters:

Protocol Compatibility: The substitute part must support RS422 and/or RS485 communication protocols.

Receiver Configuration: The substitute must provide a 0/4 receiver configuration (4 receivers, 0 drivers).

Electrical Specifications: Supply voltage range of 4.75V to 5.25V and operating temperature range of 0°C to 70°C must be maintained.

Package Compatibility: Through-hole mounting in a 16-pin DIP package format is required for direct board-level substitution.

Data Rate: The substitute should support data rates of 15 Mbps or higher to maintain system performance.

The SN75ALS195N meets these substitution criteria, providing equivalent receiver functionality within the same electrical operating parameters and compatible package form factor.

Parameter Comparison

Engineering Selection Recommendations

For RoHS Compliance Requirements: The SN75ALS195N is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS regulations. The DS96F175CJ is RoHS non-compliant and unsuitable for new designs requiring regulatory compliance.

For Existing Legacy Systems: The DS96F175CJ remains functional for maintenance and repair of existing installations where RoHS compliance is not mandated.

Package Consideration: Both parts use 16-pin DIP through-hole packages with identical 0.300" (7.62mm) spacing, enabling direct board-level substitution without layout modifications.

Receiver Hysteresis Difference: The SN75ALS195N features 120 mV receiver hysteresis compared to 50 mV in the DS96F175CJ. This higher hysteresis provides improved noise immunity in electrically noisy environments but may affect timing-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the SN75ALS195N directly replace the DS96F175CJ on existing PCBs?

A: Yes. Both parts use identical 16-pin DIP through-hole packages with 0.300" (7.62mm) pin spacing, enabling direct socket substitution without PCB modifications.

Q: What is the primary difference between these two parts?

A: The SN75ALS195N is ROHS3 compliant while the DS96F175CJ is RoHS non-compliant. Additionally, the SN75ALS195N has 120 mV receiver hysteresis versus 50 mV in the DS96F175CJ.

Q: Are the protocol specifications identical?

A: The DS96F175CJ supports RS422 and RS485 protocols. The SN75ALS195N supports RS422 and RS423 protocols. Both provide 0/4 receiver configuration and operate within the same supply voltage and temperature ranges.

Q: Which part should be selected for new designs?

A: The SN75ALS195N is recommended for new designs due to ROHS3 compliance and improved receiver hysteresis characteristics for noise immunity.

Q: Is the data rate specification maintained in the substitute?

A: The DS96F175CJ specifies 15 Mbps data rate. The SN75ALS195N does not specify a maximum data rate in the provided parameters but maintains equivalent receiver functionality for RS422/RS423 communication.
