HD74LV393A Overview
The HD74LV393A contain two 4-bit ripple carry binary counters, which can be cascaded to create a single divide-by256 counter. The HD74LV393A is incremented on the high to low transition (negative edge) of the clock input, and each has an independent clear input. When clear is set high all four bits of each counter is set to a low level.
HD74LV393A Key Features
- VCC = 2.0 V to 5.5 V operation
- All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
- All outputs VO (Max.) = 5.5 V (@VCC = 0 V)
- Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
- Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25
