Ensuring a V alid Reset Output
Down to V
CC
= 0V
When V
CC
falls below 1V,
RESET
no longer sinks cur-
rent: it becomes an open circuit. Therefore, high-
impedance CMOS logic inputs connected to
RESET
can drift to undefined voltages. This presents no prob-
lem in most applications, since most μPs and other cir-
cuitry is inoperative with V
CC
below 1V. However, in
applications where
RESET
must be valid down to 0V,
add a pull-down resistor to ground, holding
RESET
low
(Figure 4). R1’s value is not critical; 100k
is large
enough not to load
RESET,
and small enough to pull it
to ground.
Capac itor S elec tion
The capacitor type used for C1–C4 is not critical for
proper operation; use either polarized or nonpolarized
capacitors. The charge pump requires 0.1μF capaci-
tors for 3.3V operation. For other supply voltages, refer
to Table 3 for required capacitor values. Do not use val-
ues smaller than those listed in Table 3. Increasing the
capacitor values (e.g., by a factor of 2) reduces ripple
on the transmitter outputs and slightly reduces power
consumption. C2, C3, and C4 can be increased without
changing C1's value.
However, do not increase C1
without also increasing the values of C2, C3, C4,
and C
BYPASS
, to maintain the proper ratios (C1 to
the other capacitors).
