MC14489BP

Display Drivers Overview

The MC14489BP is a Binary to Phone Pulse Converter Subsystem manufactured by NXP USA Inc. (formerly Motorola). It operates within a temperature range of -40 °C to +85 °C and utilizes a standard 5 V supply voltage. The device is housed in a 16-pin Plastic Dual In-line Package (DIP) with an inline form factor, measuring approximately 19.175 mm in length and 4.44 mm in maximum height. It features selectable make/break ratios, specifically supporting 1:2 and 1:1.5 configurations. The subsystem contains one functional unit and exhibits a maximum slew rate of 1.25 mA. The component is not RoHS compliant and has a JESD-30 code of R-PDIP-T16.

Display Drivers Feature Summary

• Converts binary signals into telephone pulse formats for communication systems
• Provides selectable make-to-break ratio settings for signal customization
• Operates reliably across extended industrial temperature ranges

Display Drivers Applications

• Telephone exchange switching equipment
• Telecommunications signaling interfaces
• Binary to pulse conversion subsystems

Display Drivers Procurement Notes

Verify the specific suffix 'BP' against official NXP documentation to confirm package type and material composition. Confirm RoHS non-compliance status prior to integration into regulated assemblies. Ensure the DIP-16 footprint matches the target PCB design constraints. Validate that the operating temperature range meets the environmental requirements of the final application.

Display Drivers Selection Notes

Select this component when a dedicated hardware solution for binary-to-pulse conversion is required. Consider the DIP-16 package if through-hole mounting is necessary for mechanical stability. Evaluate the fixed 5 V supply requirement against available power rails. Assess the need for selectable make/break ratios to determine if this specific variant fits the signaling protocol requirements.

Display Drivers Part Context

This component belongs to the legacy telecommunications circuit portfolio originally developed by Motorola and now managed by NXP Semiconductors. It serves as a specialized interface chip designed for traditional telephony infrastructure. The part represents a discrete subsystem solution rather than a general-purpose logic gate or microcontroller.
