AM26LS33ACD Application Field and Working Principle

Introduction:

The AM26LS33ACD is a low-power, low-voltage combination line driver and receiver (LDR) suitable for communication interface application requirements up to 1MBaud. The device was developed as an integrated solution and reduces the number of components needed by two. This device is a full duplex line driver that can drive up to 74 ohms of line impedance at Tx and switch up to 72 ohms of line impedance at Receiver and is suitable for uncompensated and compensated data and low-frequncy audio applications.

Application Fields:

The AM26LS33ACD is typically used in computer communications and printer interfaces. It is also used in local area networks such as Ethernet and Token ring, as well as in telephone and modem applications. In addition, the device can be used as part of an isolated channel line driver and receiver for multi-drop applications.

Features:

The AM26LS33ACD line driver receiver integrated device offers several advantages over discrete devices. It has improved ESD protection due to the combination of both a line driver and receiver in one package. It also offers a low quiescent current of 2 mA and low power consumption of 650 mW of both line driver and receiver. The device also features high ESD tolerance, high data security and fast switching speed.

Working Principle:

The AM26LS33ACD functions fundamentally as a line driver and receiver in one package and provides a full-duplex operations.The line driver consist of an enables input, a TTL/CMOS compatible logic inputs and a pair of complementary, high drive outputs.The receiver, on the other hand, consist of an enables input, a TTL compatible output and a pair of low impedance inputs.The transmit enable signal controls the line driver while the receive enable control the receiver.When transmit enable signal is high, the data is transmitted while when it is low, the outputs of the line driver are in high impedance state and the device is powered off. When receive enable signal is high, the input of the receiver is allowed while when it is low, the receiver is disabled.

Conclusion:

The AM26LS33ACD is a low-power, low-voltage combination line driver and receiver suitable for communication interface application requirements up to 1 MBaud. It offers several advantages over discrete devices and supports full-duplex operations. The device is typically used in computer communications and printer interfaces as well as local area networks such as Ethernet and Token ring, as well as in telephone and modem applications.
