Quad 2-Input Gate
MC74VHCT08A advanced high speed CMOS 2-input gate fabricated with silicon gate CMOS technology. achieves high speed operation similar equivalent Bipolar Schottky while maintaining CMOS power dissipation. VHCT inputs compatible with levels. This device used level converter interfacing 3.3V 5.0V, because full CMOS level output swings. VHCT08A input structures provide protection when voltages between 5.5V applied, regardless supply voltage. output structures also provide protection when These input output structures help prevent device destruction caused supply voltage input/output voltage mismatch, battery backup, insertion, etc. internal circuit composed three stages, including buffer output which provides high noise immunity stable output. inputs tolerate voltages allowing interface systems systems. High Speed: 4.3ns (Typ) Power Dissipation: (Max) 25°C TTL-Compatible Inputs: 0.8V; 2.0V Power Down Protection Provided Inputs Balanced Propagation Delays Designed 5.5V Operating Range Noise: VOLP 0.8V (Max) Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300mA Performance: 2000V; Machine Model 200V Chip Complexity: FETs Equivalent Gates LOGIC DIAGRAM
