AM16/32A Relay Analog Multiplexer

3. AM16/32A Specifications
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 AM16/32A in an active state (where a
clock pulse can trigger a channel advance). A
signal voltage < 0.9VDC deactivates the
AM16/32A (clock pulse will not trigger a scan
advance; AM16/32A 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.
Operational
Temperature: Standard: -25oC to +50oC
Extended: -55oC to +85oC
Operational
Humidity:
0 - 95%, non-condensing
