IS4825 DC Operating Voltages
Signal Signal Description Minimum Maximum Condition
VIN Operating Voltage 4.75V 5.25V
VIH(1) Input High (RX, CTS) 2.5V
VIL(1) Input Low (RX, CTS) 0.8V
VIH(2) Input High (TTL_INV, nWake) 0.8 x Vin
VIL(2) Input Low (TTL_INV, nWake) 0.8V
VIH(3) Input High (EXT. Trigger) 0.8 x Vin
VIL(3) Input Low (EXT. Trigger) 0.8V
VOH(1) Output High Voltage (TX,RTS) 0.8 x Vin Isource = 16 mA
VOL(1) Output Low Voltage (TX,RTS) 0.14 x Vin Isink = 16 mA
VOH(2) Output High Voltage (nBeeper, nGoodRead)
***
3.6V or 5.5V
VOL(2) Output Low Voltage (nBeeper, nGoodRead) 1.6V Isink = 25 mA
VOH(3) Output High Voltage (Power down)
***
3.6V or 5.5V
VOL(3) Output Low Voltage (Power down) 0.2V Isink = 8 mA
*** PWRDWN, nGoodRead, and nBeeper are open drain outputs w/ 100K pull-ups to VIN. Actual VOH will be determined
by the parallel resistance of the 100K pull up and any external impedance.
