Description

The HD74LVC2244A has eight line drivers with three state outputs in a 20 pin package. This device is a noninverting

buffer and has two active low enables (1

G and 2G). Each enable independently controls four buffers.

All outputs, which are designed to sink up to 12mA, include equivalent 26

Ω resistors to reduce overshoot and

undershoot.

Low voltage and high-speed operation is suitable at battery drive product (note type personal computer) and low power

consumption extends the life of a battery for long time operation.
