I 1.4V to 3.6V VCC supply operation I 3.6V tolerant inputs and outputs I 26/c58 series resistors in A port outputs I tPD (B to A) 3.4 ns max for 3.0V to 3.6V VCC I Power-down high impedance inputs and outputs I Supports live insertion/withdrawal (Note 1) I Static Drive (IOH /IOL A outputs) /c114 12 mA @ 3.0V VCC I Uses patented noise/EMI reduction circuitry I Latchup performance exceeds 300 mA I ESD performance: Human body model /c33 2000V Machine model /c33 200V Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Rat- ings. The Recommended Operating Conditions tables will define the condi- tions for actual device operation. Note 3: I O Absolute Maximum Rating must be observed. Note 4: Floating or unused pins (inputs or I/O's) must be held HIGH or LOW.

5 www.fairchildsemi.com 74VCX162245 Note 6: For CL /c32 50pF, add approximately 300ps to the AC maximum specification. Note 7: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL ) or LOW-to-HIGH (tOSLH ).
