TC74HC4040AP/AF/AFN 12-Stage Binary
Counter
The TC74HC4020A/TC74HC4040A are high speed CMOS
BINARY COUNTER/DIVIDERs fabricated with silicon gate
C2MOS technology.
They achieve the high speed operetion similar to equivalent
LSTTL while maintaining the CMOS dissipation.
The TC74HC4020A is a 14-STAGE BINARY COUNTER, and
the TC74HC4040A is a 12-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.
The TC74HC4040A provides all divided output stages, and at
Q12, a 1/4096 divided frequency will be output.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• 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) = 2~6 V
• Pin and function compatible with 4020B/4040B
Note: xxxFN (JEDEC SOP) is not available in
Japan.
