74LV244D

74系列逻辑芯片/74LV244D

DESCRIPTION

The 74LV244 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT244. The 74LV244 is an octal non-inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs 1OEand 2OE. A HIGH on nOEcauses the outputs to assume a high impedance OFF-state. The 74LV244 is identical to the 74LV240 but has non-inverting outputs.
