Note 2 All outputs loaded thresholds on input associated with output under test

Note 3 IIN and ICC 3 0V are guaranteed to be less than or equal to the respective limit

ICC for 54AC 25 C is identical to CGS74C 25 C

Note 4 Maximum test duration 2 0 ms one output loaded at a time

5 5V VCC

Note 5 ICC for 54ACT 25 C is identical to CGS74CT 25 C

Note 6 Voltage Range 5 0 is 5 0V g0 5V voltage range 3 3 is 3 3V g0 3V

Note 7 Output-to-Output Skew is defined as the absolute value of the difference between the actual propagation delay for any outputs within the same packaged

device The specifications apply to any outputs switching in the same direction either HIGH to LOW (tOSHL) or LOW to HIGH (tOSLH) or in opposite directions both

HL and LH (tOST) tOSHL and tOSLH are characterized and guaranteed by design 1 MHz

Note 8 Part-to-part skew is defined as the absolute value of the difference between the propagation delay for any outputs from device to device The parameter is

specified for a given set of conditions (i e capacitive load VCC temperature of outputs switching etc ) Parameter guaranteed by design

Note 9 Load capacitance includes the test jig
