74HC244D.653, Два шинных формирователя [SO-20]

The 74HC244D, 653 is a 8-bit Buffer/Line Driver with non-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 that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.

• Input CMOS level
• Octal bus interface
• Complies with JEDEC standard no. 7A
