ML65244

August 1996 ML65244/ML65L244* High Speed Dual Quad Buffer/Line Drivers 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. FEATURES s Low propagation delay — 1.7ns ML65244 2.0ns ML65L244 s Fast Dual 4-bit TTL level buffer/line driver with tri-state capability on the output (two 4-bit sections) 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 FCT244 type pinout s Applications include high speed cache memory, main memory, processor bus buffering, and graphics cards BLOCK DIAGRAM *This Part Is Obsolete VCC 20 VCC 2G 19 1G 1 YAO 18 BO 17...
