General description
The 74LV4020 is a low-voltage Si-gate CMOS device and is pin and function compatible with the 74HC4020 and 74HCT4020.

FEATUREs
■ Optimized for low-voltage applications: 1.0 V to 5.5 V
■ Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
■ Typical LOW-level output voltage (peak) or output ground bounce: VOL(p) < 0.8 V at VCC = 3.3 V and Tamb = 25 °C
■ Typical HIGH-level output voltage (valley) or output VOH undershoot: VOH(v) > 2 V at VCC = 3.3 V and Tamb = 25 °C
■ ESD protection:
    ◆ HBM EIA/JESD22-A114-C exceeds 2000 V
    ◆ MM EIA/JESD22-A115-A exceeds 200 V.
■ Multiple package options
■ Specified from −40 °C to +80 °C and from −40 °C to +125 °C.

APPLICATIONs
■ Frequency dividing circuits
■ Time delay circuits
■ Control counters
