These inputs utilize a positive feedback resistor. The input current is negligible when the input is at either supply rail. 6. An “edge” is defined as a transition through the transmitter or receiver input thresholds. Electrical Specifications Test Conditions: VCC = 3.15V to 5.5V, C1 - C4 = 0.1µF; VCC = 3V, C1 - C4 = 0.22µF; Unless Otherwise Specified. Typicals are at TA = 25 oC (Continued) PARAMETER TEST CONDITIONS TEMP (oC) MIN TYP MAX UNITS ICL3238E |
