Logic - Buffers, Drivers, Receivers, Transceivers

The 74F545SCX is a member of the family of buffer/drivers/receivers/transceivers that includes the standard logic in the CMOS logic family. It features input/output capability of TTL logic levels and its advanced design provides high speed, low power and decreased quiescent current. It is intended for use as a memory address driver, as a bus transceiver, as a line receiver and transmitter, as a bus buffer and transceiver, and as a wide variety of other uses.

Appliation Fields

The 74F545SCX can be used in a wide variety of applications. It is suitable for many applications such as system buses, local area networks, signal processing, audio/video signal control, remote sensing and data acquisition, medical instruments, clocks, counters, computers, and mobile communication systems.

Working Principle

The 74F545SCX has four independent logic elements. Each of these elements can be configured as a buffer, driver, receiver, or transceiver. Each buffer/transceiver can operate in either the low-power standby mode or the active mode. In standby mode, the output is tristated, and no power is drawn. In active mode, data is transmitted between input and output pins at the logic level of the device.

The transceiver is designed to support up to a six-bit bus. A control signal can select the direction of data flow, allowing the bus to operate in either the input or output mode. A "flow-through" feature is included that can help reduce propogation delay when both sides of the bus are connected by short connections.

The receiver is designed for use in applications with multiple data rates and with different logic families. The portion of the device which handles the transmission rate is isolated from the rest and can be assumed to complete its operation after the required number of clock cycles. Inputs are provided for setting the required data rate.

The driver portion of the device is designed to be used as either a 4-bit driver or as a single-bit driver. The buffers are designed to be used as an input or an output buffer. The drivers can be configured to provide either TTL voltage levels or CMOS voltage levels.

The 74F545SCX is an integrated logic component with many functions that can help in many different applications. Its small size and low power consumption make it an ideal choice for a wide range of applications.
