Notes:
2. See the last page of this specification for Group A subgroup testing information.
3. A pull-up resistor to VCC on the CS input is required to keep the device deselected during VCC power-up. Otherwise current will exceed values given (CY7C148
only).
4. For test purposes, not more than 1 output should be shorted at one time. Duration of the short circuit should not exceed 30 seconds.
5. Tested initially and after any design or process changes that may affect these parameters.
