1. Unless otherwise specified, min./max. limits apply across the recommended operating temperature range. All typical are
given for VCC = 5 V and TA = 25 °C
2. Skew is defined as the difference in propagation delays between complementary outputs at the 50 % point.
3. Output disable time is the delay from the control input being switched to the output transistors tuning off. The actual disable
times are less than indicated due to the delay added by RC time constant of the load.
4. CPD determines the no load dynamic power consumption, PD = CPDVCC2, f = ICCVCC, and the no load dynamic current
consumption, PD = CPD VCCf + ICC .
