Voltages are referenced to GND (ground = 0 V). LIMITS SYMBOL PARAMETER TEST CONDITIONS -40 °C to +85°C -40 °C to +125°C UNIT MIN TYP1 MAX MIN MAX ICC Quiescent supply current; MSI VCC = 3.6 V; VI = VCC or GND; IO = 0 20.0 160 µA ∆ICC Additional quiescent supply current per input VCC = 2.7 V to 3.6 V; VI = VCC – 0.6 V 500 850 µA NOTE: 1. All typical values are measured at Tamb = 25°C. AC CHARACTERISTICS GND = 0V; tr = tf ≤ 2.5ns; CL = 50pF; RL = 1KΩ CONDITION LIMITS SYMBOL PARAMETER WAVEFORM CONDITION –40 to +85 °C –40 to +125 °C UNIT VCC(V) MIN TYP1 MAX MIN MAX 1.2 65 tPHL/tPLH Propagation delay Figures 1 2 2.0 22 43 51 ns tPHL/tPLH gy An to Yn Figures 1, 2 2.7 16 31 38 ns 3.0 to 3.6 122 25 30 1.2 70 tPHL/tPLH Propagation delay Figures 1 2 2.0 24 44 54 ns tPHL/tPLH gy En to Yn Figures 1, 2 2.7 18 33 40 ns 3.0 to 3.6 132 26 32 NOTES: 1.
