ML65245**/ML65L245*
High Speed Octal Buffer Transceivers
GENERAL DESCRIPTION
The ML65245 and ML65L245 are non-inverting octal
transceivers. The high operating frequency (50MHz
driving a 50pF load) and low propagation delay (ML65245
– 1.7ns, ML65L245 – 2ns) make them ideal for very high
speed applications such as processor bus buffering and
cache and main memory control.
These transceivers 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
ML65245 and ML65L245 conform to the pinout and
functionality of the industry standard FCT245 and are
intended for applications where propagation delay is
critical to the system design.
Note: This part was previously numbered ML6580.
FEATURES
s Low propagation delay — 1.7ns ML65245
2.0ns ML65L245
s Fast 8-bit TTL level transceiver 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 FCT245 type pinout
s Applications include high speed cache memory, main
memory, processor bus buffering, and graphics cards
