DC Electrical Characteristics
(V
IN
= 4.5V to 5.5V, T
A
= -40 to 85°C unless otherwise noted.
Typical values are at T
A
=25°C)
AC Electrical Characteristics
(V
IN
= 4.5V to 5.5V, T
A
= -40 to 85°C unless otherwise noted.
Typical values are at T
A
=25°C)
Notes:
1. Measured with outputs open and ST toggling at 100kHz, 50% duty cycle
2. RST is an open drain output
3. Guaranteed by design and not subject to production testing.
4. PBRST must remain low for greater than 20ms to guarantee a reset
