12-Stage Ripple-Carry Binary Counter
The TC7MH4040FK is an advanced high speed CMOS 12-stage
ripple-carry binary counter fabricated with silicon gate C²MOS
technology.
It achieves the high speed operation similar to equivalent
bipolar schottky TTL while maintaining the CMOS low power
dissipation.
Setting CLR to high resets the counter to low.
A negative transition on the CK input brings one increment
into the counter.
This counter provides all divided output stages, and at Q12, a
1/4096 divided frequency will be output.
An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
Weight: 0.02 g (typ.)
This device can be used to interface 5 V to 3 V systems and two
supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and
input voltages.
Features
• High speed: f_max = 210 MHz (typ.) (V_CC = 5 V)
• Low power dissipation: I_CC = 4 μA (max) (Ta = 25°C)
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Power down protection is provided on all inputs.
• Balanced propagation delays: t_pLH ≈ t_pHL
• Wide operating voltage range: V_{CC (opr)} = 2~5.5 V
• Low noise: V_OLP = 1.5 V (max)
• Pin and function compatible with 74HC4040
