| Description | The ADM3222ARWZ-REEL is a low-power RS-232 line driver and receiver transceiver from Analog Devices, designed to provide reliable serial communication between low-voltage digital systems and standard RS-232 interfaces. The device integrates two RS-232 transmitters, two RS-232 receivers, an internal charge-pump voltage converter, shutdown control, and receiver enable functionality in a single compact IC. The ADM3222ARWZ-REEL operates from a single 3.0V to 5.5V supply, making it suitable for both 3.3V and 5V embedded systems. Its integrated charge-pump circuitry generates the positive and negative voltages required for compliant RS-232 signaling without the need for separate positive and negative power supplies. The device incorporates 2 drivers and 2 receivers, providing two complete bidirectional RS-232 communication channels. This configuration is well suited for microcontrollers, processors, industrial controllers, communication equipment, and embedded systems requiring conversion between CMOS/TTL-level UART signals and RS-232 voltage levels. The ADM3222 supports data communication rates of at least 460kbps, providing sufficient bandwidth for conventional serial communication as well as higher-speed RS-232 applications. The transmitter and receiver architecture is designed to maintain reliable communication while meeting applicable EIA/TIA-232 electrical interface requirements. An integrated charge-pump voltage converter requires only small external capacitors to generate the RS-232 driver supply rails. This architecture minimizes external component count, reduces PCB area, and simplifies implementation compared with discrete level-shifting circuits or solutions requiring multiple power rails. The device includes a dedicated shutdown function that significantly reduces supply current when the RS-232 interface is not required. In shutdown mode, power consumption can be reduced to the microampere range, making the ADM3222 particularly useful in portable, battery-powered, and energy-sensitive equipment. A separate receiver enable control allows the receiver outputs to be placed into a high-impedance state without disabling the entire transceiver. This provides additional flexibility in systems using shared buses, power-management schemes, or multiple communication interfaces. The RS-232 receiver inputs are designed to tolerate the relatively high positive and negative signal voltages associated with standard serial interfaces while converting them into logic-level outputs suitable for direct connection to microcontrollers, UARTs, FPGAs, and other digital logic devices. The transmitter section converts low-voltage CMOS/TTL logic signals into compliant RS-232 output voltage levels. This integrated level translation eliminates the need for discrete transistor-based conversion circuitry and provides consistent electrical characteristics across temperature and supply variations. The ADM3222ARWZ-REEL is specified for an industrial operating temperature range of -40°C to +85°C, making it suitable for industrial control, instrumentation, communication equipment, and other systems exposed to demanding environmental conditions. The ADM3222ARWZ-REEL is supplied in a 20-lead SOIC-W wide-body surface-mount package. The WZ ordering designation identifies the wide SOIC package with lead-free construction, while the REEL suffix indicates tape-and-reel packaging suitable for automated SMT production. The ADM3222ARWZ-REEL is widely used in industrial control equipment, RS-232 communication ports, embedded computers, microcontroller systems, instrumentation, data acquisition equipment, point-of-sale terminals, diagnostic equipment, communication gateways, networking equipment, serial programming interfaces, industrial automation systems, portable instruments, and general-purpose UART-to-RS-232 interface applications requiring reliable dual-channel serial level conversion. |
