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 imped ance.

* Continuous Scan Mode current will vary based on object size, distance, and type.
The numbers listed above are typical.
** To conserve power for battery operated devices, Honeywell recommends using a power switch to operate
the scan engine.
