Counter Single 14-Bit Binary UP 16-Pin SOL

The TC74HC4020 are high speed CMOS BINARY COUNTER/DIVIDERs fabricated with silicon gate C²MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS dissipation. The TC74HC4020A is a 14-STAGE BINARY COUNTER Setting CLR to high resets the counter to low. A negative transition on the CK input brings one increment into the counter.The TC74HC4020A provides 12 divided outputs: 1’st stage and stage 4 thru stage 14. At Q14, a 1/16384 divided frequency will be output. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

• High speed: fmax = 73 MHz (typ.) at Vcc = 5 V
• Low power dissipation: Icc = 4 µA (max) at Ta = 25°C
• High noise immunity: Vnih = Vnil = 28% Vcc (min)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |Ioh| = Iol = 4 mA (min)
• Balanced propagation delays: tpLH = tpHL
• Wide operating voltage range: Vcc (opr) = 2 to 6 V
• Pin and function compatible with 4020B/4040B
