SP5730
Preliminary Information
Electrical Characteristics (continued)
Tamb= -40oC to 85oC, Vcc= 4.5 to 5.5V
These characteristics are guaranteed by either production test or design. They apply within the specified
ambient temperature and supply voltage unless otherwise stated.

Notes:
1. Output ports high impedance on power up, with data, clock, and enable at logic ‘0’
2. If the REF/COMP output is not used, the output should be left open circuit or connected to Vcc, and disabled by
setting RE = 0
3. Bi-directional port. When used as an output, the input logic state is ignored. When used as an input the port should
be switched in to high impedance (off) state.
