Unless otherwise stated, all typical values are measured at Tamb = 25°C 2. Typical values are measured at VCC = 3.3 V. AC WAVEFORMS VM = 1.5 V at VCC ≥ 2.7 V; VM = 0.5 V × VCC at VCC < 2.7 V. VOL and VOH are the typical output voltage drop that occur with the output load. SV00567 V M E INPUT nY OUTPUT V M tPLH tPHL GND V CC V OL V OH Figure 1. Enable input (E) to output (nY) propagation delays and output transition times. SV00568 V M nI 0 , nI1 , S INPUT nY OUTPUT V M tPLH tPHL GND V CC V OL V OH Figure 2. Data inputs (nln) and common data select input (S) to output (nY) propagation delays. TEST CIRCUIT PULSE GENERATOR RT VI D.U.T.
