3.3 V octal D-type ﬂip-ﬂop; 3-state

[1]

Typical values are measured at VCC = 3.3 V and Tamb =25 °C.

[2]

For valid test results, data must not be loaded into the ﬂip-ﬂops (or latches) after applying power.

[3]

Unused pins at VCC or GND.

[4]

This is the bus hold overdrive current required to force the input to the opposite logic state.

[5]

This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V

a transition time of 100

µs is permitted. This parameter is valid for T

amb =25 °C only.

[6]

ICC is measured with outputs pulled to VCC or GND.

[7]

This is the increase in supply current for each input at the speciﬁed voltage level other than VCC or GND.
