M74HC390 Dual decade counter Features ■ HIgh Speed: fMAX = 79MHz (Typ.) at VCC = 6V ■ Low power dissipation: ICC = 4µA (Max.) at TA = 25°C ■ High noise immunity: VNIH = VNIL = 28 % VCC (Min.) ) s t( c u d DIP-16 ■ Balanced propagation delays: tPLH ≅ tPHL ■ Wide operating voltage range: VCC (Opr) = 2V to 6V ■ Pin and function compatible with 74 series 390 Description e t le SO-16 o r P o s b O ) The M74HC390 is an high speed CMOS dual decade counter fabricated with silicon gate C2MOS technology. s ( t c u d o This dual decade counter contains two independent ripple carry counters. Each counter is composed of a divide by two and divide by five counter. The divide by two and divide by five counters can be cascaded to form dual decade, dual biquinary, or various combination up to a single divide by 100 counter. r P e t e l o Each 4-bit counter is increased on the high to low transition (negative edge) of the clock input, and each has an independent clear input. When clear is set low all four bits of each counter are set to low. This enables count truncation and allows the implementation of divide by N counter configuration. All inputs are equipped with protection circuits against static discharge and transient excess voltage. s b O Order codes Part number Package Packaging M74HC390B1R DIP-14 Tube M74HC390RM13TR SO-14 Tape and reel July 2006 Rev 2 1/17 www.st.com 17 Contents M74HC390 Contents 1 Pin settings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.1 Pin connection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.2 Pin description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 2 Device summary . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 3 Truth table . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 4 Block and logic diagrams . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 5 Timing chart . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 6 Maximum rating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 ) s t( c u d 6.1 e t le o r P Recommended operating conditions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 o s b 7 Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 8 Test circuit . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 9 Waveforms . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 10 Package mechanical data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 O ) s ( t c u d o 11 t e l o s b O 2/17 r P e Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 M74HC390 Pin settings 1 Pin settings 1.1 Pin connection Figure 1.
