Characteristics subject to change without notice
ELECTRICAL CHARACTERISTICS
Unless otherwise stated, 1.0V
≤ VCC ≤ 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 VCC ....................................... -0.5V to 7.0V
Voltage on
ST and TD ................. -0.5V to VCC + 0.5V
Voltage on
PBRST, RESET
and RESET ............................ -0.5V to VCC + 0.5V
Notes:
(1)
PBRST is internally pulled HIGH to VCC through a nominal 40kΩ
resistor (RPU).
(2)
RESET is an open drain output on the CAT1232LP.
(3) RESET remains within 0.5V of VCC on power-down until VCC falls
below 2V. RESET remains within 0.5V of ground on power-down
until VCC falls below 2.0V.
Maximum Junction Temperature ...................... 125
°C
Storage Temperature Range ............ -65
°C to +150°C
Lead Soldering Temperature (10 sec) .............. 300
°C
Operating Temperature Range ........... -40
°C to +85°C

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