ICL3222CV RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The ICL3222CV is a 2/2 full-duplex RS232 transceiver manufactured by Renesas Electronics Corporation in a 20-TSSOP surface mount package. This part is classified as obsolete, with 32,830 units currently in stock. The ICL3222CV operates across a 3V to 5.5V supply range with a 250 kbps data rate and 300 mV receiver hysteresis, suitable for legacy RS232 communication interfaces requiring low-voltage operation.

Due to the obsolete product status, identifying equivalent and substitute parts is necessary for design continuity, long-term availability assurance, and potential performance upgrades in new production runs or redesigns.

Duplex: Full
Package: 20-TSSOP or compatible 20-pin surface mount packages
Supply Voltage Range: 3V ~ 5.5V
Mounting Type: Surface Mount

Secondary Compatibility Factors:

Data Rate: Minimum 250 kbps (higher rates are acceptable)
Receiver Hysteresis: 300 mV or 400 mV (minor variation acceptable)
Operating Temperature: 0°C ~ 70°C minimum (extended ranges acceptable)

Engineering Selection Recommendations

Direct Renesas Equivalents (ICL3222CVZ, ICL3222CVZ-T): These parts maintain identical electrical specifications to the ICL3222CV while offering ROHS3 compliance and active product status. ICL3222CVZ is available in tube packaging with 7,083 units in stock. ICL3222CVZ-T is supplied in tape and reel format with 795 units available. Both are recommended for direct replacement in existing designs requiring RoHS compliance.

Texas Instruments Parametric Equivalents (MAX3222ECPWR, TRS3222ECPW): MAX3222ECPWR and TRS3222ECPW provide identical 2/2 RS232 transceiver functionality with doubled data rate capability (500 kbps vs. 250 kbps) while maintaining the same supply voltage and operating temperature range. MAX3222ECPWR has 4,400 units in stock and active status. TRS3222ECPW has 1,468 units available but is classified as Last Time Buy. Both are ROHS3 compliant.

Texas Instruments Upgrade Options (MAX3222EIPWR, TRS3222EIPWR): These parts extend the operating temperature range to -40°C ~ 85°C with 500 kbps data rate capability. MAX3222EIPWR offers the highest inventory availability at 63,200 units with active status. TRS3222EIPWR provides 5,930 units in stock. Both are suitable for applications requiring extended temperature operation and higher data throughput.

Analog Devices Similar Parts (ADM3222 Series): The ADM3222 series (ARSZ, ARSZ-REEL, ARSZ-REEL7, ARUZ variants) provides 2/2 RS232 transceiver functionality with 460 kbps data rate and 400 mV receiver hysteresis. ADM3222ARUZ maintains the 20-TSSOP package with 1,563 units in stock. ADM3222 variants in 20-SSOP package (0.209", 5.30mm width) offer higher inventory levels (up to 28,600 units for ARSZ-REEL7) but require PCB layout adjustment due to package width difference. All ADM3222 variants support -40°C ~ 85°C operation and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can ICL3222CVZ directly replace ICL3222CV without design changes?

A: Yes. ICL3222CVZ maintains identical electrical specifications, package footprint (20-TSSOP), and pinout. The primary differences are ROHS3 compliance and active product status. No circuit modifications are required.

Q: What is the difference between ICL3222CVZ and ICL3222CVZ-T?

A: Both parts are electrically identical. ICL3222CVZ is supplied in tube packaging, while ICL3222CVZ-T is supplied in tape and reel format. Selection depends on assembly process requirements and volume needs.

Q: Can MAX3222ECPWR replace ICL3222CV?

A: Yes, with design verification. MAX3222ECPWR is a parametric equivalent with identical supply voltage (3V ~ 5.5V), operating temperature (0°C ~ 70°C), and package (20-TSSOP). The 500 kbps data rate is backward compatible with 250 kbps applications. Verify pinout compatibility before implementation.

Q: Why do some substitutes have different receiver hysteresis values?

A: Receiver hysteresis (300 mV vs. 400 mV) affects noise immunity thresholds. The ICL3222CV specifies 300 mV. Analog Devices ADM3222 series specifies 400 mV. Both values are within RS232 standard tolerances. Higher hysteresis provides improved noise rejection in electrically noisy environments.

Q: What is the difference between 20-TSSOP and 20-SSOP packages?

A: Both are 20-pin surface mount packages. 20-TSSOP has a body width of 0.173" (4.40mm), while 20-SSOP has a body width of 0.209" (5.30mm). PCB footprints are not interchangeable. Verify package compatibility before selecting ADM3222 SSOP variants.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitutes except the original ICL3222CV are ROHS3 compliant. ICL3222CVZ and ICL3222CVZ-T are the direct Renesas equivalents with ROHS3 certification. Texas Instruments and Analog Devices variants are all ROHS3 compliant.

Q: Which substitute offers the best long-term availability?

A: MAX3222EIPWR from Texas Instruments offers the highest inventory (63,200 units) with active product status and extended temperature range (-40°C ~ 85°C). This part is recommended for new designs requiring long-term supply assurance.

Q: Can I use ADM3222ARSZ-REEL7 in place of ICL3222CV?

A: ADM3222ARSZ-REEL7 is functionally compatible as a 2/2 RS232 transceiver but requires PCB redesign due to package change (20-SSOP vs. 20-TSSOP). The 460 kbps data rate and 400 mV hysteresis are within acceptable parameters. Verify pinout and footprint compatibility before layout changes.
