MAX213CDW

Drivers, Receivers, Transceivers Overview

The MAX213CDW is a low-power RS-232 transceiver manufactured by Texas Instruments, designed for multi-channel communication applications. It integrates four drivers and five receivers within a single SOIC-28 package, supporting full-duplex data transmission at rates up to 120 kb/s. The device operates on a single 5 V supply with a maximum voltage of 5.5 V and a minimum of 4.5 V, drawing approximately 20 mA during active operation. It features an integrated shutdown mode to minimize power consumption when the device is not in use. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four independent drivers and five receivers for comprehensive multi-channel RS-232 connectivity.
• Includes a dedicated shutdown pin to significantly reduce power consumption during idle periods.
• Utilizes internal charge pumps to generate positive and negative voltages directly from a single 5 V supply.
• Provides robust ESD protection rated at 15 kV on all RS-232 lines to safeguard connected equipment.

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring multiple serial communication ports
• Computer peripherals and modems utilizing standard RS-232 interfaces
• Data acquisition modules needing isolated signal transmission
• Embedded systems with limited power budgets requiring low standby current

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade match the design requirements. Ensure that the procurement source provides valid traceability documentation for the Texas Instruments brand. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Check for any recent product change notices that might affect pin compatibility or electrical specifications before placing orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require four transmit and five receive channels without external voltage generation components. Compare against the TRS213 series for potential pin-compatible alternatives if cost optimization is necessary. Ensure the PCB layout accommodates the required decoupling capacitors for the internal charge pumps. Verify that the system's ground reference matches the device's common mode voltage limits for reliable signal integrity.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX213 family of low-power RS-232 transceivers from Texas Instruments. It shares functional similarities with other members like the MAX213IDB, which uses an SSOP-28 package. The device is distinct from the TRS213 series, which offers similar functionality but may differ in commercial temperature ranges and specific electrical characteristics. It serves as a direct replacement for older legacy RS-232 drivers in modern surface-mount designs.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS213CDWR is a pin-compatible alternative offering similar electrical performance. Verify that the TRS213 variant meets the specific temperature range requirements of the application, as some versions are limited to commercial grades. Ensure that the substitute part maintains the same driver and receiver count configuration.
