CD74HC93M .

产品概述

The CD74HC93M is a 4bit high speed CMOS binary Ripple Counter pin-compatible with low power Schottky TTL (LSTTL). It consists of four flip-flops internally connected to provide a divide-by-two section and a divide-by-eight section. Each section has a separate clock input (CP0 and CP1) to initiate state changes of the counter on the high to low clock transition. State changes of the Qn outputs do not occur simultaneously because of internal ripple delays. Therefore, decoded output signals are subject to decoding spikes and should not be used for clocks or strobes.

• 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
