ML65541/ML65L541*
High Speed Octal Buffer/Line Drivers
GENERAL DESCRIPTION
The ML65541 and ML65L541 are non-inverting octal
buffer/line drivers. The high operating frequency (50MHz
driving a 50pF load) and low propagation delay
(ML65541 – 1.7 ns, ML65L541 – 2 ns) 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 ML65541
and ML65L541 conform to the pinout and functionality of
the industry standard FCT541 and are intended for
applications where propagation delay is critical to the
system design.
Note: This part was previously numbered ML6581.
FEATURES
s Low propagation delay — 1.7ns ML65541
2.0ns ML65L541
s Fast 8-bit TTL level buffer/line driver with three-state
capability on the output
s TTL compatible input and output levels
s Schottky diode clamps on all inputs to handle
undershoot and overshoot
s Onboard schottky diodes minimize noise
s Reduced output swing of 0 – 4.1 volts
s Ground bounce controlled outputs, typically less
than 400mV
s Industry standard FCT541 type pinout
s Applications include high speed cache memory, main
memory, processor bus buffering, and graphics cards
