74LVT273

3.3 V octal D-type ﬂip-ﬂop

[1]

All typical values are measured at VCC = 3.3 V (unless stated otherwise) and Tamb =25 °C.

[2]

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

Increase in supply current for each input at the speciﬁed voltage level other than VCC or GND
