| Overview | 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. p-flops having interchangeable Clock and ENABLE inputs for incrementing on either the positive-going or negative-going transition. For single-unit operation the ENABLE input is maintained ”high” and the counter advances on each positive-going transition of the CLOCK. The counters are cleared by high. |
