ELECTRICAL CHARACTERISTICS
TAMB = -10°C to +80°C, VCC = +4·5V to +5·5V.
These Characteristics are guaranteed by either production test or design. They apply within the specified ambient temperature
and supply voltage ranges unless otherwise stated. Reference frequency 4MHz unless otherwise stated.

NOTES
1. Source impedance between all output ports and ground is approximately 5Ω. This should be taken into account when calculating output port
saturation voltages.
2. The recommended crystal series resistance quoted refers to all conditions including start-up.
