Absolute Maximum Ratings*
- Voltages are with respect to ground (VSS) unless otherwise stated.
* Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.
Recommended Operating Conditions
- Voltages are with respect to ground (V
SS
) unless otherwise stated.
Typical figures are at 25C and are for design aid only: not guaranteed and not subject to production testing.
DC Electrical Characteristics
- Voltages are with respect to ground (V
SS
) unless otherwise stated.
Characteristics are for clocked operation over the ranges of recommended operating temperature and supply voltage.
Typical figures are at 25C and are for design aid only: not guaranteed and not subject to production testing.
* Limits for input leakage on pin names: tdi, tck, tms and trstb are max 100uA.
AC Electrical Characteristics - Timing Parameter Measurement Voltage Levels
Note 1: Timing for output signals is based on the worst case result of the combination of TTL and CMOS thresholds.
