74LS245 Octal Bus Transceiver IC

The 74LS245 Octal Bus Transceiver IC belongs to 74XXYY IC series. The 74LS245 designed as an Octal Bus Transmitter/Receiver specifically for 8-line asynchronous 2-way data communication between data buses. The Direction Input (DR) controls the transmission of Data from bus A to bus B or bus B to bus A depending upon its logic level. The Enable input E’ used to disable the device so that the device effectively isolates. This 74LS245 IC also features:

• Hysteresis Inputs to Improve Noise Immunity
• 2-Way Asynchronous Data Bus Communication
• Input Diodes Limit High-Speed Termination Effects
• ESD > 3500 Volts

Bus transceivers designed as electronic tri-state bi-directional devices that allows the flow of data between two points.  This makes them compatible with bus-oriented systems or the bi-directional (input or output) control of interface circuitry. Moreover,  Bus transceiver exist as inverting or non-inverting, common examples are 74LS243 & LS242 IC series. Bus tranceivers are designed specifically for asynchronous two-way communication between two data buses or input/output device. Meanwhile, this transceiver allows for the transmission of data from terminals A to terminals B or the reverse depending on the logic level at the direction-control input. These IC widely used to provide bidirectional, input or output control, of either digital or analogue devices to a common shared data bus.
