• A transceiver is electronic equipment that combines a receiver and a transmitter that share common circuits Used in IT, telephony, etc. They are fixed or portable communication devices.
• The 74HC245 is an 8-bit transceiver with 3-state outputs.
• The device has output enable (OE) and transmit / receive (DIR) for steering control.
• A HIGH on OE causes the outputs to take a high impedance OFF state.
• The inputs include clamping diodes. This allows current limiting resistors to be used to interface inputs at voltages greater than VDC.
