1. General description
The 74LV245 is an 8-bit transceiver with 3-state outputs. The device features an output enable
(OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a
high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting
resistors to interface inputs to voltages in excess VCC.
