CROSS-REFERENCE ALTERNATIVE
COSMAX3222 is a Chinese-manufactured Interface Transceiver IC from COSINE (科山芯创) that cross-references to MAX3222 (MAXIM).
It is a TSSOP20 device positioned as a domestic-supply option against the imported: shorter lead times, no allocation risk and a stable price for volume production. Because the parts are not pin-identical in every case, the engineering checklist below lists what to verify before you commit.

COSMAX3222 — Interface Transceiver IC, alternative to MAX3222
COSMAX3222 is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for MAX3222 (MAXIM). Imported parts in this class are frequently subject to allocation, long lead times and steep price swings. A Chinese-manufactured equivalent removes that exposure: the parts are production-validated in industrial, consumer and automotive designs and ship from stock on a short lead time.
Cross-reference chart — which imported parts does COSMAX3222 replace?
Every imported part number that COSMAX3222 is published as a cross-reference alternative to, per the COSINE (科山芯创) 2025 selection table:
| imported part number | brand | Replaced by (this part) |
|---|---|---|
| MAX3222 | MAXIM | COSMAX3222 |
Cross-reference means functional equivalence in the same application role. It is not a blanket claim of pin-for-pin identity — confirm package, pinout and the parameters listed below before you release a design change.

What to verify before substituting COSMAX3222
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Data rate capability and the slew-rate limiting option, which directly affects EMI and cable length
- Supply range and logic-level compatibility (3.3 V vs 5 V I/O) with your controller
- Bus common-mode range and bus fault protection voltage
- ESD rating on the bus pins, and whether the was HBM or IEC-spec rated
- Fail-safe behaviour (idle, open, short, terminated) — a common and costly difference between families
- Pinout and mode-select pin behaviour, including slope-control and standby pins
- Isolation requirements if the design spans separate grounds
Typical applications
- Industrial fieldbus and factory automation
- PLC, HMI and motion-control networks
- Automotive and commercial-vehicle networks
- Building automation and metering
- Data acquisition and instrumentation
- Robotics and CNC control systems
