CD74HC4520M96 .

产品概述

The CD74HC4520M96 is a high speed CMOS dual Binary Up-Counter consists of two independent internally synchronous 4-stage counters. The counter stages are D-type flip-flops having interchangeable clock and enable lines for incrementing on either the positive-going or the negative-going transition of clock. The counters are cleared by high levels on the MASTER RESET lines. The counter can be cascaded in the ripple mode by connecting Q3to the ENABLE input of the subsequent counter while the clock input of the latter is held low.

• Positive or negative edge triggering
• Synchronous internal carry propagation
• 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
