MAXIM'S NEW PRODUCT RELEASE ANNOUNCEMENT MAX3228/MAX3229 +2.5V to +5.5V RS-232 Transceivers in UCSP FOR PRODUCT RELATED

July 27, 2001 MAXIM'S NEW PRODUCT RELEASE ANNOUNCEMENT MAX3228/MAX3229 MAX3228/MAX3229 +2.5V to +5.5V RS-232 RS-232 Transceivers in UCSP FOR PRODUCT RELATED INFORMATION CONTACT THE BUSINESS MANAGER: Kent Robinett FOR ALL OTHER INFORMATION CONTACT THE DIRECTOR OF DISTRIBUTION: Ken Bloom DATA SHEET AVAILABLE: Within 4 weeks EV KIT AVAILABLE: No ADVERTISEMENT SHOWS: Within 4 weeks PRESS RELEASE SHOWS: Within 4 weeks PRODUCT DESCRIPTION The MAX3228/MAX3229 MAX3228/MAX3229 are +2.5V to +5.5V powered EIA/TIA-232 EIA/TIA-232 and V.28/V.24 communications interfaces with low power requirements, and high data-rate capabilities, in a chip-scale package (UCSPTM). The MAX3228/MAX3229 MAX3228/MAX3229 achieve a 1µA supply current with Maxim's AutoShutdown feature. They save power without changes to existing BIOS or operating systems by entering low-power shutdown mode when the RS-232 RS-232 cable is disconnected, or when the transmitters of the connected peripherals are off. The transceivers have a proprietary low-dropout transmitter output stage, delivering RS-232 RS-232 compliant performance from a +3.1V to +5.5V supply, and RS-232 RS-232 compatible performance with a supply voltage as low as +2.5V. The dual charge pump requires only four small 0.1µF capacitors for operation from a +3.0V supply. Each device is guaranteed to run at data rates of 250kbps while maintaining RS-232 RS-232 output levels. The MAX3228/MAX3229 MAX3228/MAX3229 offer a separate power supply input for the logic interface, allowing configurable logic levels on the receiver outputs and transmitter inputs. Operating over a +1.65V to VCC range, VL provides the MAX3228/MAX3229 MAX3228/MAX3229 compatibility with multiple logic families. The MAX3229 MAX3229 contains one receiver and one transmitter. The MAX3228 MAX3228 contains two receivers and two transmitters. The MAX3228/MAX3229 MAX3228/MAX3229 are available in tiny chip-scale packaging and are specified across the extended industrial temperature range of -40°C to +85°C. See the attached data sheet page(s) for more information.
