CD74HC4040M .

产品概述

The CD74HC4040M is a 12-stage high speed CMOS binary counter. All the counter stages are flip-flops. The state of the stage advances one count on the negative clock transition of each input pulse, a high voltage level on the MR line resets all counters to their zero state. All inputs and outputs are buffered.

• Fully static operation
• Common reset
• Negative edge pulsing
• Balanced propagation delay and transition times
• Significant power reduction compared to LSTTL logic ICs
• High noise immunity
• Direct LSTTL input logic compatibility
• CMOS input compatibility
• 10 LSTTL load standard outputs
• 15 LSTTL load bus driver outputs

• Green product and no Sb/Br
