54FCT162244TEB

The 54FCT162244TEB is a member of the FCT(Fast CMOS) logic family from Fairchild Semiconductor. This device integrates a bidirectional 16-bit transceiver with a 3-state output controlled by a pair of output enable controls, one for each direction. This device is most commonly used in buses applications such as general system control, data/address multiplexing, and peripheral interfaces. It is also used in consumer applications including disc drives and keyboards.

Overview

The 54FCT162244TEB is a 16-bit transceiver that combines two 8-bit bidirectional transceivers, each with a 3-state output controlled by output enable controls. It contains two 8-bit data registers which can be read and written in either direction. The device is designed to be used in applications such as Ethernet, SCSI and SCSI-2. It is composed of two identical 8-bit bidirectional transceivers; each with a separate output enable control, one for each direction. The enable inputs of each device are tied together to simplify its control.

Working Principle

The 54FCT162244TEB works by transferring data from one device to another. It is a bidirectional transceiver and each of the 8-bit data registers can be read and written in either direction. Data is transferred on the rising edge of the clock signal. Data isread from the register when the output enable of the register is high, and written to the register when the input enable is high. The output enable control of each transceiver is tied together, simplifying control.

The 54FCT162244TEB is designed to optimize power consumption. It features on-chip termination resistors to reduce the current consumption and provides balanced outputs to improve AC signal quality. It also works with both CMOS and TTL compatible inputs.
