MAX3314CKA+T

Overview

The MAX3314CKA+T is an RS-232-compatible transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin SOT23 package. It operates with external +5V and -5V power supplies within a range of 4.75V to 5.25V for VCC and -4.75V to -5.25V for V-. The device features one transmitter and one receiver, supporting data rates up to 460kbps with a typical propagation delay of 0.15µs. Operating supply current is typically 30µA, reducing to 1µA in shutdown mode. It functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Low-power shutdown capability reduces supply current to 1µA while keeping the receiver active
• RS-232-compatible output levels maintained at high data rates with low-dropout transmitter stage
• Receiver remains functional during shutdown mode for continuous signal monitoring

Applications

• Digital Cameras
• Personal Digital Assistants (PDA)
• GPS Receivers
• Point-of-Sale (POS) Terminals
• Telecommunications Equipment

Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official manufacturer documentation. Ensure the specific batch corresponds to the intended application environment. Cross-reference part numbers carefully to avoid confusion between commercial and extended temperature variants.

Selection Notes

Select this component when a single-channel RS-232 interface is required in a compact SOT23 footprint. Consider the 460kbps data rate limit and ±5V dual-supply requirement. Evaluate the need for active receiver operation during system sleep states. Verify compatibility with TTL/CMOS logic levels on the input and output pins.

Part Context

This part belongs to the MAX3314 family of RS-232 transceivers designed for low-voltage, low-power applications. The 'C' designation indicates a commercial temperature range, while 'KA' specifies the 8-pin SOT23 package. The '+' suffix denotes lead-free packaging compliant with environmental standards.

Replacement Considerations

Direct pin-compatible alternatives include other members of the MAX3314 family such as MAX3314EKA for extended temperature ranges or MAX3314CSA for SOIC packages. Verify electrical specifications match before substitution.
