ML65T541

May 1997 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. FEATURES s Low propagation delay — 2.0ns s Fast 8-bit buffer/line driver with three-state capability on the output s Schottky diode clamps on all inputs to handle undershoot and overshoot s Onboard schottky diodes minimize noise s Ground bounce controlled outputs s Industry standard FCT541 type pinout s Applications include high speed cache memory, main memory, processor bus buffering, and graphics cards BLOCK DIAGRAM *Some Packages Are Obsolete VCC 20 VCC OE1 1 OE2 19 A0 2 A1 3 A2 4 A3 5 A4 6 A5 7 A6 8 A7 9 10 GND 18 B0 17 B1 16 B2 15 B3 14 B4 13 B5 12 B6 11 B7 *Some packages are obsolete ML65T541 PIN CONFIGURATION 20-Pin QSOP 1G A0 YB0 A1 YB1 A2 YB2 A3 YB3 GND 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 VCC 2G YA0 B0 YA1 B1 YA2...
