Product details

RS-232 transceiver for industrial serial links

The ICL3221EIVZ-T7A: It operates from a 3V to 5.5V supply, so it can run directly off a 3.3V or 5V rail without an extra regulator — one less part on the BOM. Data rate is 250 kbps. The 500 mV receiver hysteresis filters noise on long cable runs.

The 0.173-inch (4.40 mm) width is standard for TSSOP-16. For prototype runs, the cut-tape option avoids minimum reel quantities.

ROHS3 compliant — no exemptions that would complicate EU or California market shipments.

Frequently asked questions

What is the data rate of the ICL3221EIVZ-T7A?

250 kbps. That supports standard UART rates up to 115200 baud with headroom for higher-speed custom protocols within the RS-232 voltage swing.

Can the ICL3221EIVZ-T7A replace the ICL3221EIVZ?

The ICL3221EIVZ-T7A is the Tape & Reel variant of the base ICL3221EIVZ. The electrical specs (data rate, supply range, temperature grade) are identical. The T7A suffix denotes the reel packaging; the bare die and package are the same. Yes, it is a drop-in replacement for the ICL3221EIVZ on the same PCB footprint.
