Datasheet Summary
Dual decade counter
Features
- HIgh Speed: fMAX = 79MHz (Typ.) at VCC = 6V
- Low power dissipation:
)ICC = 4µA (Max.) at TA = 25°C t(s- High noise immunity: cVNIH = VNIL = 28 % VCC (Min.) du- Balanced propagation delays: rotPLH ≅ tPHL P- Wide operating voltage range: teVCC (Opr) = 2V to 6V le- Pin and function patible with 74 series 390 soDescription ObThe M74HC390 is an high speed CMOS dual -decade counter fabricated with silicon gate )C2MOS technology. t(sThis dual decade counter contains two ucindependent ripple carry counters. Each counter dis posed of a divide by two and divide by five rocounter. The divide by two and divide by five Pcounters can be cascaded to form...
