AM16/32 Relay Analog Multiplexer

FIGURE 1. AM16/32 Relay Multiplexer

3. AM16/32 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 AM16/32 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.

Operational

Temperature:

Standard: -25

C to +50

Extended: -55

C to +85

Operational

Humidity: 0 - 95%, non-condensing
