_______________Detailed Desc ription
As shown in the block diagram of Figure 2, the Maxim
ICL7665 combines a 1.3V reference with two com-
parators, two open-drain N-channel outputs, and two
open-drain P-channel hysteresis outputs. The refer-
ence and comparator are very low-power linear CMOS
circuits, with a total operating current of 10
μ
A maxi-
mum, 3
μ
A typical. The N-channel outputs can sink
greater than 10mA, but are unable to source any cur-
rent. These outputs are suitable for wire-OR connections
and are capable of driving TTL inputs when an external
pull-up resistor is added.
The ICL7665 Truth Table is shown in Table 1. OUT1 is
an inverting output; all other outputs are noninverting.
HYST1 and HYST2 are P-channel current sources
whose sources are connected to V+. OUT1 and OUT2
are N-channel current sinks with their sources connect-
ed to ground. Both OUT1 and OUT2 can drive at least
one TTL load with a V
OL
of 0.4V.
In spite of the very low operating current, the ICL7665
has a typical propagation delay of only 75
μ
s. Since the
comparator input bias current and the output leakages
are very low, high-impedance external resistors can be
used. This design feature minimizes both the total sup-
ply current used and loading on the voltage source that
is being monitored.

OUT1 is an inverting output; all others are noninverting. OUT1
and OUT2 are open-drain, N-channel current sinks. HYST1
