DS16F95J Equivalent & Substitute Parts

Part Overview

The DS16F95J is a half-duplex RS422/RS485 transceiver manufactured by Texas Instruments, housed in an 8-CDIP package. This interface IC is designed for serial communication applications requiring robust noise immunity and differential signaling. The part is currently obsolete, making equivalent substitutes necessary for new designs, repairs, and system upgrades. Identifying compatible alternatives ensures continuity in applications where this transceiver was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS16F95J is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Protocol compatibility: RS422/RS485 half-duplex operation
• Driver/Receiver configuration: 1/1 topology
• Duplex mode: Half-duplex only
• Package type: 8-pin DIP variants (8-CDIP or 8-CERDIP)
• Through-hole mounting requirement
• Supply voltage overlap with 4.5V ~ 5.5V range
• Operating temperature range that encompasses or exceeds -55°C to 180°C

The identified substitutes meet these core requirements while maintaining functional equivalence for RS422/RS485 serial communication applications.

Parameter Comparison

Engineering Selection Recommendations

HI-4853CRH is an active substitute offering extended operating temperature range (-55°C ~ 200°C) and wider supply voltage tolerance (3.15V ~ 5.5V). Package dimensions differ slightly (0.314" vs. 0.300"), requiring PCB layout verification for through-hole mounting compatibility. RoHS non-compliance status matches the original part.

MAX485MJA is an active substitute with RoHS3 compliance, suitable for applications requiring environmental and regulatory adherence. Supply voltage range (4.75V ~ 5.25V) is narrower than the original specification, and maximum operating temperature (125°C) is lower than the DS16F95J. Package dimensions (0.300", 7.62mm) match the original exactly, enabling direct PCB compatibility. This part is appropriate for new designs with standard industrial temperature requirements.

Selection between substitutes depends on application-specific constraints: temperature extremes, supply voltage stability, regulatory compliance requirements, and PCB layout flexibility.

Frequently Asked Questions (FAQ)

Q: Can HI-4853CRH and MAX485MJA be used interchangeably with DS16F95J?

A: Both parts share the same RS422/RS485 half-duplex 1/1 transceiver topology and through-hole 8-pin DIP packaging. Functional substitution is valid provided application operating temperature and supply voltage requirements fall within each part's specified range. PCB layout must accommodate the HI-4853CRH's slightly larger package dimension (0.314" vs. 0.300").

Q: What is the impact of different receiver hysteresis values?

A: DS16F95J specifies 50 mV hysteresis; MAX485MJA specifies 70 mV. Higher hysteresis improves noise immunity in electrically noisy environments but may reduce sensitivity to small differential signals. HI-4853CRH hysteresis is not specified in available data. Application noise characteristics determine whether this difference is significant.

Q: Are there supply voltage compatibility concerns?

A: DS16F95J operates at 4.5V ~ 5.5V. MAX485MJA operates at 4.75V ~ 5.25V, a narrower range that excludes the lower and upper extremes of the original specification. HI-4853CRH operates at 3.15V ~ 5.5V, providing broader low-voltage tolerance. Verify your power supply stability against each part's requirements.

Q: Does operating temperature range affect substitution decisions?

A: DS16F95J operates to 180°C; HI-4853CRH to 200°C; MAX485MJA to 125°C. Applications requiring operation above 125°C must use HI-4853CRH or DS16F95J. Standard industrial applications typically operate within 0°C ~ 70°C, making all three parts functionally equivalent for temperature.

Q: What are the package compatibility implications?

A: DS16F95J and MAX485MJA use identical 8-CDIP packages (0.300", 7.62mm), enabling direct PCB substitution. HI-4853CRH uses 8-CERDIP (0.314", 7.98mm), a slightly larger package requiring PCB layout verification to ensure through-hole pad spacing and component clearance compatibility.

Q: Does RoHS compliance affect part selection?

A: MAX485MJA is RoHS3 compliant; DS16F95J and HI-4853CRH are RoHS non-compliant. New designs subject to RoHS regulations must use MAX485MJA. Legacy systems or applications without RoHS requirements can use any of the three parts.
