MAX3320LEAP

Overview

The MAX3320LEAP is a dual RS-232 transceiver integrated with a microprocessor power-on reset circuit, operating from a +3V to +5.5V supply. It features a proprietary low-dropout transmitter output stage and a dual charge pump requiring only four 0.1µF capacitors. The device supports data rates up to 250kbps and includes AutoShutdown Plus for 4µA standby current. The LEAP suffix indicates an extended temperature range of -40°C to +85°C and a RESET threshold of 4.63V. It is housed in a 20-pin SSOP package.

Feature Summary

Integrates a precise power-on reset supervisor with a true RS-232 transceiver
AutoShutdown Plus reduces supply current to 4µA when inputs are inactive
Proprietary low-dropout transmitter ensures compliance at 3V to 5.5V
Receivers remain active during shutdown to detect wake-up signals

Applications

Palmtop Computers
Portable/Battery-Powered Equipment
Hand-Held Equipment
Peripherals
Printers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact reset threshold voltage and temperature rating. Confirm that the component is available in the required 20-pin SSOP package format. Ensure compatibility with the target system's logic levels and power supply constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring combined RS-232 communication and power supervision in a compact form factor. The LEAP variant is suitable for industrial or wide-temperature environments compared to commercial grade options. Consider the 4.63V reset threshold to ensure it aligns with the system's brown-out detection requirements.

Part Context

The MAX3320 belongs to a family of low-power RS-232 transceivers designed for portable electronics. Variants such as MAX3320A, B, and T differ primarily in their reset threshold voltages and operating temperature ranges. The MAX3320LEAP specifically provides extended temperature coverage and a higher reset threshold for 5V systems.

Replacement Considerations

Direct substitutes include other MAX3320 variants like MAX3320EAP or MAX3320CAP depending on the required temperature range and reset threshold. Verify pin compatibility and electrical specifications when cross-referencing with similar RS-232 transceivers from Analog Devices or Maxim Integrated.
