DS14196WM RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The DS14196WM is a full-duplex RS232 transceiver IC manufactured by Texas Instruments, featuring 5 drivers and 3 receivers in a 20-SOIC surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The part operates across a 5V to 12V supply range with a maximum data rate of 230.4 Kbps and supports operating temperatures from 0°C to 70°C.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS14196WM are qualified based on the following critical parameters that determine functional equivalence:

• Protocol: RS232 full-duplex transceiver
• Driver/Receiver Configuration: 5 drivers and 3 receivers
• Package Type: 20-SOIC surface mount form factor
• Operating Temperature Range: 0°C to 70°C
• Mounting Type: Surface mount

The substitute parts listed below maintain these core electrical and mechanical specifications. However, substitute parts operate within a narrower supply voltage range (4.5V ~ 5.5V) compared to the original part (5V ~ 12V), and feature a specified receiver hysteresis of 500 mV. These differences represent design improvements in later generations while maintaining functional compatibility for standard RS232 applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain functional equivalence to the DS14196WM through identical driver/receiver configuration, RS232 protocol implementation, and 20-SOIC package geometry. The substitute parts offer improved compliance status, with all options rated as ROHS3 compliant compared to the original part's RoHS non-compliant designation.

GD75323DWR and GD75323DW (GD series, Last Time Buy status) provide the most direct functional replacement with specified receiver hysteresis of 500 mV and 120 Kbps data rate capability.

SN75196DWR and SN75196DW (SN series, Last Time Buy status) offer equivalent 5/3 transceiver functionality with 500 mV receiver hysteresis and identical package specifications.

Packaging format selection between Cut Tape (CT) and Tube options depends on assembly process requirements and component handling procedures. Both packaging formats maintain identical electrical performance and MSL rating of 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can DS14196WM be directly replaced with GD75323DWR or SN75196DWR?

A: Yes. Both substitute parts maintain the 5/3 full-duplex RS232 transceiver configuration, identical 20-SOIC package geometry, and matching operating temperature range (0°C to 70°C). The primary difference is the narrower supply voltage range (4.5V ~ 5.5V versus 5V ~ 12V) in substitute parts. Verify your system operates within the 4.5V to 5.5V window before substitution.

Q: What is the difference between Cut Tape (CT) and Tube packaging?

A: Cut Tape and Tube are packaging and delivery formats that do not affect electrical performance or pin configuration. Cut Tape packaging is suitable for automated pick-and-place assembly, while Tube packaging is used for manual handling and lower-volume applications. Select based on your manufacturing process requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (GD75323DWR, SN75196DWR, GD75323DW, SN75196DW) are ROHS3 compliant, whereas the original DS14196WM is RoHS non-compliant. This represents an improvement in environmental compliance for new designs and procurement.

Q: What does "Last Time Buy" product status mean?

A: Last Time Buy indicates that the manufacturer has announced end-of-life for the part and will accept orders only until a specified cutoff date. After this date, the part will no longer be available. Substitute parts with Last Time Buy status should be evaluated for long-term availability planning.

Q: Is the receiver hysteresis specification critical for substitution?

A: The 500 mV receiver hysteresis specified in substitute parts represents a design parameter that improves noise immunity in RS232 communication. This specification is not present in the original DS14196WM datasheet parameters provided. Both configurations are functionally compatible for standard RS232 applications operating within the specified voltage and temperature ranges.
