Renesas Electronics TTL/CMOS Line Transceiver IC, CMOS Logic Family, Surface Mount TSSOP 16-Pin Package ICL3221ECVZ

Renesas Electronics ICL3221ECVZ is a CMOS logic family line transceiver integrated circuit designed for efficient RS-232 communication interface applications. Housed in a 16-pin Thin Shrink Small Outline Package (TSSOP), this device supports surface mount technology for modern PCB designs. It operates on a low supply voltage range of 3V to 5.5V while consuming only 1 microampere of supply current in low power mode, making it suitable for power-sensitive industrial and embedded systems.

The IC supports single-ended inputs with TTL/CMOS output logic levels, enabling reliable full-duplex communication. Its max propagation delay time of 0.15 microseconds ensures fast signal transmission, optimizing performance in data communication equipment. The device is rated for operation between -40°C and 125°C, extending its usability to harsh industrial environments and automotive applications that do not require the automotive standard.

Physically, the compact dimensions of 5mm length, 6.4mm width, and 1.2mm height promote efficient space utilization on densely packed circuit boards. The product complies with international standards including V.28/V.24 for terminal interface, RoHS environmental compliance, IEC61000-4-2 for electrostatic discharge protection, and EIA/TIA-232 for serial communication protocols, ensuring durability and regulatory conformity.

Renesas Electronics manufactures this model with high precision in the Philippines, branded under the ICL32xxE series, guaranteeing consistent quality and industry reliability. The device's combination of low supply current, fast propagation delay, compact footprint, and broad temperature tolerance makes it ideal for use in industrial control systems, telecommunications equipment, laboratory instrumentation, and embedded electronic devices requiring robust and reliable serial data communication.
