M74HC4518 (M74HC4518 / M74HC4520) DUAL COUNTER

The M54/74HC4518/4520 are high speed CMOS DUAL 4 BIT BINARY COUNTERS fabricated in sili2 con gate C MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. They consists of two identical internally synchronous 4-stage counters. The counter st.
