3 / 22 page CY74FCT16952T CY74FCT162952T CY74FCT162H952T 3 Note: 7. Typical values are at VCC= 5.0V, TA= +25˚C ambient. 8. This parameter is specified but not tested. 9. Pins with bus hold are described in the Pin Description. 10. Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter tests, IOS tests should be performed last. 11. Tested at +25˚C. Electrical Characteristics Over the Operating Range Parameter Description Test Conditions Min.
