ML65245**/ML65L245*

High Speed Octal Buffer Transceivers

BLOCK DIAGRAM

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
