MAX214CPI

Drivers, Receivers, Transceivers Overview

The MAX214CPI is a +5V RS-232 transceiver providing an 8-line, software-configurable DTE or DCE interface. It operates on a single +5V supply with four 1µF external capacitors for the dual charge pump. The device supports data rates up to 116kbps and features a shutdown mode consuming typically 20µA while keeping receivers active. It is housed in a 28-pin Plastic DIP package and functions within a temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable DTE/DCE configuration eliminates the need for null modem cables
• Integrated dual charge pump requires only four 1µF external capacitors
• Low-power shutdown mode maintains receiver activity for ring indicator detection

Drivers, Receivers, Transceivers Applications

• AT-Compatible Laptop Computers
• AT-Compatible Desktop Computers
• Modems, Printers, and Other Peripherals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CPI' corresponds to the commercial temperature range (0°C to +70°C) and 28-pin Plastic DIP package. Confirm that the ordering information matches the required pinout and electrical characteristics for the target application design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-chip solution for both DTE and DCE serial ports is required. Ensure the system design accommodates the necessary 1µF charge-pump capacitors and provides a stable +5V supply. Consider the 116kbps maximum data rate and the specific thermal requirements of the commercial grade variant.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX214 family of programmable RS-232 transceivers. The 'C' designation indicates the commercial temperature range, while 'P' denotes the plastic DIP package style. It serves as a complete interface solution for legacy serial communication standards without requiring separate cable swaps.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX214EPI offers the same functionality but extends the operating temperature range to -40°C to +85°C. Verify if the industrial temperature rating is necessary for the deployment environment before substituting.
