ML65T541*
3.3V High Speed Octal Buffer/Line Driver
GENERAL DESCRIPTION
The ML65T541 is a non-inverting octal buffer/line driver.
The high operating frequency (66MHz driving a 50pF
load) and low propagation delay (2ns) make it ideal for
very high speed applications such as processor bus
buffering cache/main memory control.
The ML65T541 uses a unique analog implementation to
eliminate the delays inherent in traditional digital designs.
Schottky clamps reduce undershoot and overshoot, and
special output driver circuits limit ground bounce. The
ML65T541 conforms to the pinout and functionality of the
industry standard FCT541 and is intended for applications
where propagation delay is critical to the system design.
