Notes:
ˉˉˉˉˉˉ
ˉˉˉˉˉˉ
(1) PBRST is internally pulled HIGH to V CC through a nominal 40 k ? resistor (RPU).
(2) RESET is an open drain output on the CAT1232LP.
(3) RESET remains within 0.5 V of V CC on power-down until V CC falls below 2 V. RESET remains within 0.5 V of ground on power-down until
V CC falls below 2.0 V.
ˉˉ
(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 ≥ 2.7 V.
(6) Measured with V CC < 2.7 V.
