Package Type: SOIC-16 (Small Outline Integrated Circuit) Pin Count: 16 pins Package Description: The AM26C32IDR is packaged in a 16-pin surface-mount package for easy integration into PCBs.Circuit Principle Instructions:
The AM26C32IDR is used for differential signaling, which involves transmitting data across a pair of wires where one carries the signal and the other carries its inverse (differential signal). This type of signaling provides better noise immunity and is suitable for high-speed data transmission.
The IC has four independent drivers (A1, A2, A3, A4) with corresponding output pins (Y1, Y2, Y3, Y4). Each driver operates in differential mode, meaning it outputs both a positive and a negative signal. The A pins (A1 to A4) are non-inverting inputs, while the B pins (B1 to B4) are inverting inputs. The Y pins are the corresponding outputs for each driver. The signal output on Y is the inverted differential signal based on the inputs A and B.The AM26C32IDR is often used in applications such as:
Long-distance data transmission Industrial control systems Communication systems where signal integrity and noise immunity are critical.20 Common FAQ for the AM26C32IDR:
