TRSF3232IDRG4 Equivalent & Substitute Parts

Part Overview

The TRSF3232IDRG4 is a 2/2 full-duplex RS232 transceiver manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This interface IC operates across a 3V to 5.5V supply range and supports data rates up to 1 Mbps with a 300 mV receiver hysteresis specification. The device is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TRSF3232IDRG4 is determined by strict equivalence across the following critical parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 2/2 configuration
• Duplex Mode: Full
• Data Rate: 1 Mbps minimum
• Voltage Supply Range: 3V ~ 5.5V
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Receiver Hysteresis: 300 mV

Substitute parts are grouped into two categories: parametric equivalents from Texas Instruments with identical electrical specifications and operating temperature ranges, and manufacturer-recommended alternatives from MaxLinear, Inc. that meet the core functional requirements with noted variations in operating temperature range and moisture sensitivity level.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring full compatibility with the TRSF3232IDRG4 across the complete operating temperature range of -40°C to 85°C, select from the Texas Instruments parametric equivalents: SN65C3232DR, SN65C3232EDR, or TRSF3232EIDR. All three devices are active products with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and handling flexibility.

The MaxLinear SP3232EUCN-L and SP3232EUCN-L/TR are manufacturer-recommended alternatives suitable for applications operating within the 0°C to 70°C temperature range. These devices maintain functional equivalence across all core RS232 transceiver parameters but feature MSL 2 moisture sensitivity, requiring controlled storage conditions. The SP3232EUCN-L/TR variant in Tape & Reel packaging offers the highest inventory availability at 32,900 units.

For new designs, prioritize active product status devices. For legacy system support where the TRSF3232IDRG4 is obsolete, the Texas Instruments SN65C3232EDR provides the largest current inventory at 20,400 units, ensuring supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the SP3232EUCN-L series replace the TRSF3232IDRG4 in all applications?

A: The SP3232EUCN-L and SP3232EUCN-L/TR are functionally equivalent for RS232 transceiver operation within their specified 0°C to 70°C operating temperature range. Applications requiring operation below 0°C or above 70°C must use Texas Instruments equivalents (SN65C3232DR, SN65C3232EDR, or TRSF3232EIDR) rated to -40°C to 85°C.

Q: What is the difference between the Texas Instruments substitute options?

A: SN65C3232DR, SN65C3232EDR, and TRSF3232EIDR are parametric equivalents with identical electrical specifications, operating temperature range (-40°C to 85°C), and MSL 1 rating. Differences exist only in base product number designation and packaging availability. SN65C3232EDR has the highest inventory availability.

Q: Does packaging format affect electrical performance?

A: No. The 16-SOIC package format is identical across all substitute options. Packaging differences (Cut Tape, Digi-Reel, Tube, or Tape & Reel) affect handling, storage, and procurement logistics only, not electrical or functional performance.

Q: What is the significance of MSL rating differences?

A: MSL 1 (Unlimited) devices like the TRSF3232IDRG4 and Texas Instruments substitutes have no moisture sensitivity restrictions and can be stored indefinitely under normal conditions. MSL 2 (1 Year) devices like the MaxLinear SP3232 series require controlled storage and must be used within one year of packaging opening. For high-volume or long-term inventory applications, MSL 1 devices are preferred.

Q: Are all substitute parts ROHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant or RoHS compliant, meeting environmental regulatory requirements equivalent to the original TRSF3232IDRG4.
