Operates From Single 5-V Supply
Designed to Be Interchangeable With
Motorola MC3486
description
The MC3486 is a monolithic quadruple differential line receiver designed to meet the specifications of ANSI
Standards EIA/TIA-422-B and EIA/TIA-423-B and ITU Recommendations V.10 and V.11. The MC3486 offers
four independent differential-input line receivers that have TTL-compatible outputs. The outputs utilize 3-state
circuitry to provide a high-impedance state at any output when the appropriate output enable is at a low logic
level.
The MC3486 is designed for optimum performance when used with the MC3487 quadruple differential line
driver. It is supplied in a 16-pin package and operates from a single 5-V supply.
The MC3486 is characterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential-input voltage, are with respect to network ground terminal.
2. Differential-input voltage is measured at the noninverting input with respect to the corresponding inverting input.
