ELECTRICAL CHARACTERISTICS
Unless otherwise stated, 1.0V
≤
V
CC
≤
5.5V and over the operating temperature range of -40
°
C to +85
°
C. All
voltages are referenced to ground.
ABSOLUTE MAXIMUM RATINGS*
Voltage on V
CC
....................................... -0.5V to 7.0V
Voltage on
ST
and TD ................. -0.5V to V
CC
+ 0.5V
Voltage on
PBRST
,
RESET
and RESET ............................ -0.5V to V
CC
+ 0.5V
Notes:
(1)
PBRST
is internally pulled HIGH to V
CC
through a nominal 40k
resistor (R
PU
).
(2)
RESET
is an open drain output on the CAT1232LP.
(3) RESET remains within 0.5V of V
CC
on power-down until V
CC
falls
below 2V. RESET remains within 0.5V of ground on power-down
until V
CC
falls below 2.0V.
Maximum Junction Temperature ...................... 125
°
C
Storage Temperature Range ............ -65
°
C to +150
°
C
Lead Soldering Temperature (10 sec).............. 300
°

(4) Must not exceed the minimum watchdog time-out period (t
TD
).
The watchdog circuit cannot be disabled. To avoid a reset,
ST
must be strobed.
(5) Measured with V
CC
≥
2.7V.
(6) Measured with V
CC
< 2.7V.
