DESCRIPTION

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.

FEATURES

? Optimized for Low Voltage applications: 1.0 to 3.6V

? Accepts TTL input levels between VCC = 2.7V and VCC = 3.6V

? Typical VOLP (output ground bounce)  0.8V @ VCC = 3.3V, Tamb = 25°C

? Typical VOHV (output VOH undershoot)  2V @ VCC = 3.3V, Tamb = 25°C

? Two 4-bit binary counters with individual clocks

? Divide-by any binary module up to 28 in one package

? Two master resets to clear each 4-bit counter individually

? Output capability: standard

? ICC category: MSI
