This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 5. Unless otherwise specified, all voltages are referenced to ground. 6. The maximum allowable values of RX and CX are a function of leakage of capacitor CX, the leakage of the HC4538, and leakage due to board layout and surface resistance. Values of RX and CX should be chosen so that the maximum current into pin 2 or pin 14 is 30mA. Susceptibility to externally induced noise signals may occur for RX > 1MΩ. 7. θJA is measured with the component mounted on an evaluation PC board in free air.
