Description

The HD74LV244A has eight line drivers with three-state outputs in a 20-pin package. Four non-inverters are included

in one circuit. Each circuit can be independently controlled by the enable signal 1

OE or 2OE, which enables outputs

when receiving a low-level signal. Low-voltage operation is suitable for battery-powered products (e.g., notebook

computers), and the low-power consumption extends the battery life.
