74HC245-Q100; 74HCT245-Q100 Octal bus tranceiver; 3-state Rev. 1 22 July 2013 Product data sheet 1. General description The 74HC245-Q100; 74HCT245-Q100 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 that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications. 2. Features and benefits Automotive product qualification in accordance with AEC-Q100 (Grade 1) Specified from 40 C to +85 C and from 4 [ ... ]
