MM88C30N

Buffers, Drivers, Receivers, Transceivers Overview

The MM88C30N is a dual differential line driver manufactured by Fairchild Semiconductor, now part of onsemi. It integrates dual four-input NAND or AND logic functions within its design. The device operates with a supply voltage range of 3V to 15V and features high noise immunity. It utilizes a 14-lead Plastic Dual-In-Line (PDIP) package conforming to JEDEC MS-001 standards. The component supports an operating temperature range from -40°C to +85°C and includes specific electrical characteristics for propagation delay and output drive capabilities suitable for digital data transmission applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides differential outputs designed to eliminate ground-loop errors in signal transmission

Buffers, Drivers, Receivers, Transceivers Applications

• Digital data transmission over twisted pair lines
• Interfacing CMOS digital signal sources with varying voltage levels
• Driving clock lines and data lines in industrial environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin, as the datasheet indicates Fairchild Semiconductor as the original publisher while onsemi is the current entity. Confirm the package type is the 14-lead PDIP (N14A) and not the SOIC variant. Ensure the ordering code matches the specific suffix requirements if tape and reel packaging is needed, which requires appending the letter 'X' to the base order number.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when differential signaling is required to mitigate ground-loop issues in noisy environments. It is appropriate for designs needing integrated logic gating combined with line driving. Consider the 3V to 15V operating range for compatibility with various logic families. Verify that the thermal resistance and power dissipation limits fit the system's thermal management strategy.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the MM88C29/MM88C30 series of CMOS line drivers. While the MM88C29 provides single-ended driving, the MM88C30 focuses on differential transmission. Both share similar logic structures but differ in output configuration. The series is designed for robust digital communication interfaces where signal integrity across transmission lines is critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the MM88C30M in SOIC packaging or equivalent parts like the SN75ALS191. Verify pinout compatibility and logic function equivalence before substitution.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the MM88C30 handle voltage level interfacing?

The absence of clamp diodes to VCC in the input protection circuitry allows a CMOS digital signal source to operate at a VCC voltage greater than that of the MM88C30 line driver.

What logic functions are included in the MM88C30?

In addition to being a dual differential line driver, the device performs dual four-input NAND or dual four-input AND functions.
