ST Micro M74HC244B Octal Buffer/Line Driver Tri-state DIL20

Manufactured by STMicrolectronics - Part # M74HC244B - DIP20 through hole package

FEATURES

• Input levels: For 74HC244: CMOS level
• Octal bus interface
• Non-inverting 3-state outputs

DESCRIPTION

The 74HC244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1¬OE and 2¬OE), each controlling four of the 3-state outputs. A HIGH on n¬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 V_CC.
