74LVT640 3.3 V Octal transceiver with direction pin; inverting; 3-state Rev. 4 — 23 February 2021 Product data sheet 1. General description The 74LVT640 is an 8-bit inverting 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. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs 2. Features and benefits • 3-state buffers • Wide supply voltage range from 2.7 to 3.6 V • Overvoltage tolerant inputs to 5.
