SYNCHRONOUS 4-BIT BINARY  
COUNTER WITH ASYNCHRONOUS  
RESET, 5 VOLT TOLERANT I/O  
FEATURES:  
features an internal look-ahead carry and can be used for high-speed  
counting. Synchronousoperationisprovidedbyhavingallflip-flopsclocked  
simultaniouslyonthepositive-goingedgeoftheclock(CP). Outputs (Q0 to  
Q3)ofthe counters maybe presettoa highorlowlevel. Alowlevelatthe

• 0.5 MICRON CMOS Technology  
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using  
machine model (C = 200pF, R = 0)  
VCC = 3.3V ± 0.3V, Normal Range  
VCC = 2.7V to 3.6V, Extended Range  
• CMOS power levels (0.4μ W typ. static)  
• Rail-to-Rail output swing for increased noise margin  
All inputs, outputs, and I/Os are 5V tolerant  
• Supports hot insertion
