DS14C89AN

Drivers, Receivers, Transceivers Overview

The DS14C89AN is a quad CMOS receiver designed for RS-232 interface applications. Manufactured by Texas Instruments, this component operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating voltage of 5 V. It supports data rates up to 20 kb/s and features four single-ended receivers. The device draws a maximum operating current of 900 uA and dissipates up to 1.513 W of power. It is housed in an MDIP-14 package suitable for through-hole mounting and functions reliably across a temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four independent CMOS receivers for serial communication
• Provides ESD protection capabilities for signal integrity
• Supports standard RS-232 signaling protocols

Drivers, Receivers, Transceivers Applications

• RS-232 serial communication interfaces
• Industrial control systems requiring reliable data reception
• Embedded systems utilizing legacy serial ports

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer designation, as National Semiconductor was acquired by Texas Instruments. Confirm the presence of the NOPB suffix for lead-free compliance if required by current assembly standards. Check availability status as the component may be discontinued or subject to last-time buy restrictions. Ensure the MDIP-14 package matches the target PCB footprint requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad receiver configuration is needed without integrated drivers. Verify that the 20 kb/s data rate meets the system's transmission speed requirements. Ensure the 4.5 V to 5.5 V supply voltage aligns with the available power rails. Consider the through-hole MDIP-14 package constraints during layout planning.

Drivers, Receivers, Transceivers Part Context

This part belongs to the DS14C89A series of RS-232 interface ICs. It serves as the receiving counterpart to driver components like the DS14C88. The device is part of Texas Instruments' portfolio following the acquisition of National Semiconductor. It is distinct from transceiver pairs, offering only receive functionality.

Drivers, Receivers, Transceivers Replacement Considerations

Check for DS14C89AN/NOPB for lead-free variants. Evaluate DS14C89AM for SOIC package alternatives. Verify compatibility with other quad receivers in the same family.
