Nexperia 74HCT244D,653 Octal-Channel Buffer & Line Driver, 3-State, 20-Pin SOIC

High-Speed CMOS Logic
Operating Voltage 4.5 to 5.5 V
Compatibility: Input TTL, Output CMOS

The 74HC244, 74HCT244 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 (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.
