FAIRCHILD SEMICONDUCTOR  74VHC4040M.  芯片, 逻辑芯片 - 74VHC, 二进制计数器

The is an advanced high-speed CMOS Device fabricated with silicon gate CMOS technology. It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHC4040 is a 12-stage counter which increments on the negative edge of the input clock and all outputs are reset to a low level by applying a logical high on the reset input. An input protection circuit insures that 0 to 7V can be applied to the inputs without regard to the supply voltage. This device can be used to interface 5 to 3V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages. This product is general usage and suitable for many different applications.
