TC74VHC4040F集成电路（IC）的计数器除法器规格书PDF中文资料

12-Stage Ripple Carry Binary Counter

The TC74VHC4040 is an advanced high speed CMOS 12-STAGE BINARY COUNTER/DIVIDER 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.

特性 Features

• High speed: fmax = 210 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)

• Power down protection is provided on all inputs.

• Balanced propagation delays: tpLH ∼ − tpHL

• Wide operating voltage range: VCC (opr) = 2 V to 5.5 V

• Low noise: VOLP = 1.5 V (max)

• Pin and function compatible with 74HC4040
