MAX3316EUP+T

Overview

The MAX3316EUP+T is a dual-transmitter, dual-receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +2.25V to +3.0V supply and utilizes a proprietary low-dropout transmitter output stage with a dual charge pump. The device supports data rates up to 460kbps and requires only four 0.1µF capacitors for operation. It features a guaranteed 4V/µs slew rate and operates within a temperature range of -40°C to +85°C. The component draws 300µA during normal operation and enters a 1µA shutdown mode via the SHDN pin. It is housed in a 20-pin TSSOP package.

Feature Summary

• Proprietary low-dropout transmitter output stage enabling RS-232-compatible performance from +2.25V to +3.0V
• AutoShutdown Plus feature allows automatic entry into low-power shutdown mode when idle
• Guaranteed 460kbps data rate with worst-case loads of 3kΩ in parallel with 1000pF
• Logic-level READY output asserts when the charge pump is regulating and the device is ready

Applications

• Palmtop Computers
• Hand-Held Instruments
• Cellular Phones
• GPS
• Handy Terminals

Procurement Notes

Verify the specific suffix 'EUP' confirms the extended temperature range (-40°C to +85°C) and the 20-pin TSSOP package configuration. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the ordering information matches the exact part number to avoid functional discrepancies related to driver/receiver counts or control features.

Selection Notes

Select this component for applications requiring RS-232 communication at low voltages without external voltage triplers. It is suitable for systems needing minimal external capacitance and low power consumption. Consider the MAX3317 if manual shutdown control is preferred over AutoShutdown Plus. Verify that the 460kbps data rate meets the system requirements.

Part Context

The MAX3316EUP+T belongs to the MAX3316–MAX3319 family of 2.5V, 1µA, 460kbps RS-232-compatible transceivers. This family is designed for portable devices where power efficiency and low voltage operation are critical. The E suffix denotes the extended industrial temperature range, while UP indicates the 20-pin TSSOP package.

Replacement Considerations

Public confirmed substitute part numbers: MAX3316EUP, MAX3317EUP, MAX3318EUP, MAX3319EUP.
