Abstract
Circuitry 200 is provided for transferring data across a conductive line 201. A driver 202 is provided for transmitting data across the line 201, the driver 202 receiving data at a first high voltage level and a low voltage level and driving the line 201 at the low voltage level and a second high voltage level, the second high voltage level being less than the first high voltage level. A receiver 206 is provided for receiving data transmitted on line 201 by driver 202. The receiver includes a differential amplifier 207-210 having a first input coupled to line 201 and a second input coupled to a voltage source providing a reference voltage V.sub.ref. Receiver 206 further includes a current source transistor 212 for coupling a common node 213 of the differential amplifier to a source providing a voltage at the first high voltage level, the differential amplifier outputting data at said low voltage level and said first high voltage level.
