ADM5180JP Overview

The ADM5180JP is an 8-channel differential line receiver made for digital communication systems handling up to 200 kB/s. It supports input signals based on EIA-232-E, EIA-422A, and CCITT standards like V.10, V.11, V.28, X.26, and X.27. These are converted into TTL/CMOS outputs, making the device a strong replacement for UC5180C and NE5180 models. Built on BiCMOS technology, it offers fast performance with less than 25 mW power use. It features a built-in failsafe that ensures steady output even during input faults, managed by FS1 and FS2 pins. You can get the ADM5180JP in 28-pin DIP or PLCC packaging, making it flexible for different builds.

Features of ADM5180JP

Multiple Line Receivers in One Chip

You get eight differential line receivers in a single ADM5180JP chip. This setup helps reduce board space and wiring complexity, making your design more efficient and easier to manage.

Works With Common Communication Standards

The ADM5180JP supports input signals that follow standards like EIA-232E, 423A, 422A, and CCITT V.10, V.11, and V.28. This gives you broad compatibility with many systems in digital communication.

Runs on a Single +5 V Supply

You only need one +5 V power source to operate the ADM5180JP. This simplifies your power design and makes integration into your system smoother.

Handles High Input Voltage

Its differential inputs can withstand up to ±25 V, so you don't have to worry about signal spikes or faults damaging the device during normal use.

Internal Hysteresis for Signal Stability

Built-in hysteresis improves noise immunity by preventing small signal fluctuations from affecting output states. It helps maintain steady and clear signal processing.

Energy-Efficient Operation

This device uses low-power CMOS technology, drawing only around –3.5 mA. It's a good fit for systems that need to keep energy use low without sacrificing performance.

Clean and Reliable Outputs

You get outputs that work with TTL and CMOS levels. That means you can connect the ADM5180JP directly with other logic devices without needing extra converters.

Two Package Types to Fit Your Setup

Whether you prefer through-hole or surface mounting, the ADM5180JP comes in both 28-pin DIP and 28-lead PLCC versions, giving you flexibility during assembly.

Easy Upgrade Option

The ADM5180JP is a low-power drop-in replacement for older models like UC5180C and NE5180, making it simple to update your design without major changes.

Functional Block Diagram of ADM5180JP

The functional block diagram of ADM5180JP shows eight differential receivers labeled A through H. Each receiver takes two input signals—one inverting and one noninverting—and processes them to provide a single-ended output (AO to HO). FS1 and FS2 are control pins used to manage the failsafe operation, where FS1 affects receivers A to D, and FS2 controls E to H. This setup helps maintain reliable signal detection even when the input is idle or disconnected. The layout is simple and clear, making it easy to follow the signal flow from input to output.
