AM16/32B Relay Analog Multiplexer

FIGURE 1. AM16/32B Relay Multiplexer

3. AM16/32B 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 3.3 VDC and 8 VDC

holds the AM16/32B in an active state (where a

clock pulse can trigger a channel advance). A

signal voltage < 0.9VDC deactivates the

AM16/32B (clock pulse will not trigger a scan

advance; AM16/32B is also reset).

Clock

On the transition from <1.5 V to >3.3 V, a scan

advance is actuated on the leading edge of the clock

signal; clock pulse should be a minimum of 1 ms

wide; maximum voltage is 8 VDC.

Operational

Temperature:

Standard: -25

C to +50

Extended: -55

C to +85

Operational

Humidity:

0 - 95%, non-condensing

Dimensions:

Length – 23.9 cm (9.4")

Width - 10.2 cm (4.0")

Depth - 4.6 cm (1.8")
