Description
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
74LS245 Octal Bus Transceiver IC is identical to the standard versions and offers a propagation delay time of 50ns. This IC operates at a supply voltage at a range between 4.75V and to a maximum of 5.25V. This IC designed for operation over the full military temperature range of −0°C to 75°C. Meanwhile, 74LS245 manufactured in 20−pin plastic PDIP wide-body surface-mount packages.
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.
