74LV245 Octal bus transceiver; 3-state Rev. 5 — 28 September 2021 Product data sheet 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. 2.
