74HC245D.653, Восьмиканальный двунаправленный …The 74HC245D, 653 is a 8-bit Bus Transceiver with non-inverting 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 of VCC., Input CMOS level, Octal bidirectional bus interface, Complies with JEDEC standard JESD7A
