Power
*
:
Unregulated 12 VDC
Minimum Operating Voltage:
from –55C to +40C = 11.3 VDC;
from +40C to +85C = 11.8 VDC
(See Figure 2 for relay actuation times vs.
temperature and supply voltage.)
Current Drain:
Quiescent: < 210 uA
Active: 6 mA typical in “2 x 32” mode
11 mA typical in “4 x 16” mode
Reset
*
:
A continuous signal between 3.5 VDC and 16 VDC
holds the AM16/32 in an active state (where a clock
pulse can trigger a channel advance). A signal
voltage < 0.9VDC deactivates the AM16/32 (clock
pulse will not trigger a scan advance; AM16/32 is
also reset).
Clock
*
:
On the transition from <1.5 V to >3.5 V, a scan
advance is actuated on the leading edge of the clock
signal; clock pulse should be a minimum of 1 ms
wide.
