Software Controlled (Manual) Powerdown
Most devices in the ICL32XXE family provide pins that allow
the user to force the IC into the low power, standby state.
On the ICL3222E and ICL3241E, the powerdown control is
via a simple shutdown (SHDN) pin. Driving this pin high
enables normal operation, while driving it low forces the IC
into its powerdown state. Connect SHDN to V
CC
if the
powerdown function isn’t needed. Note that all the receiver
outputs remain enabled during shutdown (see Table 2). For
the lowest power consumption during powerdown, the
receivers should also be disabled by driving the EN input
high (see next section, and Figures 2 and 3).
The ICL3221E, ICL3223E, and ICL3243E utilize a two pin
approach where the FORCEON and FORCEOFF inputs
determine the IC’s mode. For always enabled operation,
FORCEON and FORCEOFF are both strapped high. To
switch between active and powerdown modes, under logic
or software control, only the FORCEOFF input need be
driven. The FORCEON state isn’t critical, as FORCEOFF
dominates over FORCEON. Nevertheless, if strictly manual
control over powerdown is desired, the user must strap
FORCEON high to disable the automatic powerdown
circuitry. ICL3243E inverting (standard) receiver outputs also
disable when the device is in manual powerdown, thereby
eliminating the possible current path through a shutdown
peripheral’s input protection diode (see Figures 2 and 3).
