MAX3316CAE+T

Overview

The MAX3316CAE+T is a single-driver, single-receiver RS-232 transceiver from the MAX3316–MAX3319 family. It operates on a single +2.25V to +3.0V supply and utilizes a dual charge pump for voltage generation. The device supports data rates up to 460kbps with a guaranteed 4V/µs slew rate. It features a 300µA operating supply current and includes an INVALID output signal. The component is housed in a 16-pin SSOP package and is rated for commercial temperature ranges of 0°C to +70°C.

Feature Summary

• Proprietary low-dropout transmitter stage enables RS-232 compatibility at low voltages
• Dual charge pump architecture requires only four small capacitors
• INVALID output pin indicates receiver input validity status

Applications

• Palmtop Computers
• Hand-Held Instruments
• GPS Devices

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact package type and temperature range. Confirm RoHS compliance status through the datasheet or authorized distributor channels before procurement.

Selection Notes

Select this part for applications requiring RS-232 communication within a strict 2.25V to 3.0V power budget. Ensure the design accommodates the required four external 0.1µF capacitors for the internal charge pumps.

Part Context

This component belongs to the MAX3316–MAX3319 series of low-voltage RS-232 transceivers. While sharing core functionality with other members of the family, it is distinguished by its single-transmitter/receiver configuration and lack of AutoShutdown Plus features found in the MAX3318/MAX3319 variants.

Replacement Considerations

The MAX3316CAP serves as a direct replacement offering the same electrical specifications but packaged in a 20-pin TSSOP format instead of the 16-pin SSOP.

FAQ

Does the MAX3316CAE+T include AutoShutdown Plus?

No, the MAX3316 does not feature AutoShutdown Plus; this function is exclusive to the MAX3318 and MAX3319 devices.

What is the purpose of the INVALID output?

The INVALID output asserts low when no valid RS-232 voltage levels are detected on the receiver inputs.
