Philips 74LV393
The 74LV393 is a low–voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT393. The 74LV393 is a dual 4-bit binary ripple counter with separate clocks (1CP, 2CP) and master reset (1MR, 2MR) inputs to each counter. The operation of each half of the ‘‘393’’ is the same as the ‘‘93’’ except no external clock connections are required.| Part No. | 74LV393 |

DESCRIPTION
The counters are triggered by a HIGH-to-LOW transition of the clock inputs. The counter outputs are internally connected to provide clock inputs to succeeding stages. The outputs of the ripple counter do not change synchronously and should not be used for high-speed address decoding.
