Frequently Asked Questions
What is the supply voltage range for the MAX3221IDB?
The MAX3221IDB operates from a 3V to 5.5V single supply. It includes an integrated charge pump that generates the ±5.5V RS-232 compliant voltage levels internally, eliminating the need for external bipolar supplies.
What package does the MAX3221IDB come in and how many pins does it have?
The MAX3221IDB comes in a 28-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch. This compact surface-mount package is well-suited for space-constrained PCB designs requiring RS-232 serial communication.
What is a suitable alternative to the MAX3221IDB?
A close alternative is the MAX3232IDR from Texas Instruments, which provides 2 drivers and 2 receivers with the same 3–5.5V supply range. For a pin-compatible third-party option, the SP3221EEA-L/TR from Exar offers similar functionality with shutdown mode support.
Is the MAX3221IDB RoHS compliant?
Yes, the MAX3221IDB is RoHS compliant and lead-free. Texas Instruments designates this part as meeting EU RoHS Directive requirements, making it suitable for environmentally-conscious designs and global market compliance.
What applications is the MAX3221IDB designed for?
The MAX3221IDB is designed for battery-powered portable devices, industrial handheld equipment, and embedded systems that require low-power RS-232 serial communication. Its 1µA shutdown mode and wide supply range make it ideal for power-sensitive UART-to-RS-232 interface applications.
