Описание 74HC240D,653
The 74HC240D is a 8-bit inverting Buffer/Line Driver with inverting 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE 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
• Complies with JEDEC standard JESD7A
