• Bus Extenders
• Data Communication
• Industrial Instrumentation
• Peripheral Data Communication
• Process Control Applications
• System Interfacing

Working Principle

The 54FCT162244CTEB is a bi-directional transceiver with eight channels. It operates in either a single direction (uplink), or bidirectional (uplink and downlink) mode. The direction of data flow is determined by the 3-state control pin. The device is composed of two identical 4-bit transceivers, each with an output enable input which can be used to disconnect all 8 outputs from the bus lines.

When the output enable (OE) input is low, the devices are enabled, and the data present on the data inputs (A0 to A3 and/or B0 to B3) will be transmitted to the corresponding bus lines (D0 to D7). When the OE input ishigh, all devices are in the high-impedance state, and will not drive the bus lines.

The 54FCT162244CTEB has two separate data paths and a set of controls, one for each direction. At any given moment, one data path will be enabled and transmitting data, while the other is in the high-impedance state. By reversing the OE control, the transceiver can switch between the two data paths, allowing bi-directional data transmission.

Conclusion

The 54FCT162244CTEB is a versatile bi-directional transceiver with eight channels and is suitable for a variety of digital data communication applications. Its ability to switch between uplink and downlink data paths allows it to handle multiple operations, and its compatibility with both TTL and 5V CMOS logic families makes it a highly desirable component.
