1. All I
DD
measurements taken with suitable decoupling capacitors across the power supply to suppress the transient switch-
ing currents inherent in CMOS designs (see
VDD and VSS
).
2. Typical values are at mid point of voltage range and at 25
°
C only.
3. Characteristic guaranteed by design, but not tested.
4. RUN and WAIT I
DD
: measured using an external square-wave clock source (f
OSC
= 2.1 MHz); all inputs 0.2V from rail; no
DC loads; maximum load on outputs 50pF (except OSC2 load 20pF).
WAIT I
DD
: only the timer system active; current varies linearly with the OSC2 capacitance.
WAIT and STOP I
