Working Principles

The AM26LS32ACDRE4 is a line transceiver IC that converts TTL/CMOS logic levels to differential output signals suitable for RS-422 or RS-485 applications. It operates by receiving TTL/CMOS level inputs on the A, B, C, and D pins and converting them into differential outputs on the Y, Z, YB, and ZB pins.

The receiver enable (RE) pin controls the output state of the receiver section, allowing it to be enabled or disabled as needed. The driver enable (DE) pin controls the output state of the driver section, enabling or disabling the transmission of data.

The IC is designed to operate at high speeds up to 20 Mbps while consuming low power. It provides reliable data transmission over long distances and is compatible with industry-standard RS-422 and RS-485 protocols.
