ML65244/ML65L244
High Speed Dual Quad Buffer/Line Drivers
BLOCK DIAGRAM
GENERAL DESCRIPTION
The ML65244 and ML65L244 are non-inverting dual
quad buffer/line drivers. The high operating frequency
(50MHz driving a 50pF load) and low propagation delay
(ML65244 – 1.7ns, ML65L244 – 2ns) make them ideal for
very high speed applications such as processor bus
buffering and cache and main memory control.
These buffers use a unique analog implementation to
eliminate the delays inherent in traditional digital
designs. Schottky clamps reduce under and overshoot,
and special output driver circuits limit ground bounce.
The ML65244 and ML65L244 conform to the pinout and
functionality of the industry standard FCT244 and are
intended for applications where propagation delay is
critical to the system design.
Note: This part was previously numbered ML6582.
