Is4825 Dc Operating Voltages; Current Draw @ 25°C - Metrologic IS4813 Integration Manual

IS4825 DC Operating Voltages

Signal
VIN Operating Voltage
VIH(1) Input High (RX, CTS)
VIL(1) Input Low (RX, CTS)
VIH(2) Input High (TTL_INV, nWake)
VIL(2) Input Low (TTL_INV, nWake)
VIH(3) Input High (EXT. Trigger)
VIL(3) Input Low (EXT. Trigger)
VOH(1) Output High Voltage (TX,RTS)
VOL(1) Output Low Voltage (TX,RTS)
VOH(2) Output High Voltage (nBeeper, nGoodRead)
VOL(2) Output Low Voltage (nBeeper, nGoodRead)
VOH(3) Output High Voltage (Power down)
VOL(3) Output Low Voltage (Power down)
***
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.
