Figure 2-3: FlashOut Signal Timing
TTL Active High (default)
A TTL Active High output signal is
typically used together with a TTL /
CMOS Logic Device.
The TTL Active High output signal
has the following characteristics:
• High output min. 4.5 V at 10 mA
output load, shortcut current
50 mA (+40 %/- 20 %)
• Low output max. 0.5 V at -10 mA
output load, shortcut current
-50 mA (+40 %/- 20 %)
Low Side Switch
(Open Collector)
When you select this output signal
variant, the upper transistor is deac-
tivated, which is shown by grayed
lines in the schematic.
The schematic shows a sample cir-
cuit for your flash device.
Select your flash device to ensure
that the maximum output current
never exceeds 50 mA.
