MAX3380E

Overview
19-2128; Rev 0; 8/01 +2.
35V to +5.
5V, 1µA, 2Tx/2Rx RS-232 Transceivers with ±15kV ESD-Protected I/O and Logic Pins General Description The MAX3380E/MAX3381E are +2.
35V to +5.
5V-powered EIA/TIA-232 and V.
28/V.
24 communication interfaces with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection on both the TTL and RS-232 sides.
The MAX3380E/MAX3381E have two receivers and two transmitters.
All RS-232 inputs, outputs, and logic input pins are protected to ±15kV using IEC 1000-4-2 AirGap Discharge method and the Human Body Model, and ±8kV using IEC 1000-4-2 Contact Discharge method.
The proprietary low-dropout transmitter output stage enables true RS-232 performance from a +3.
1V to +5.
5V supply with a dual charge pump.
The parts reduce the transmitter output levels to RS-232-compatible levels with no increase in supply current for supplies less than +3.
1V and greater than +2.
35V.
The +2.
35V to +5.
5V operating range is fully compatible with lithium-ion (Li+) batteries.
The charge pump requires only four small 0.
1µF capacitors for operation.
The MAX3380E/MAX3381E transceivers use Maxim’s revolutionary AutoShutdown Plus™ feature to automatically enter a 1µA shutdown mode.
These devices shut down the on-board power supply and drivers when they do not sense a valid signal transition for 30 seconds on either the receiver or transmitter inputs.
The MAX3380E is capable of transmitting data at rates of 460kbps while maintaining RS-232 output levels, and the MAX3381E operates at data rates up to 250kbps.
The MAX3381E offers a slower slew rate for applications where noise and EMI are issues.
The MAX3380E/MAX3381E have a unique V L pin that allows interoperation in mixed-logic voltage systems down to +1.
65V.
Both input and output logic levels are referenced to the VL pin.
The MAX3380E/MAX3381E are available in a space-saving TSSOP package.
