I 1.4V–3.6V VCC supply operation I 3.6V tolerant inputs and outputs I 26Ω series resistors in outputs I tPD 3.4 ns max for 3.0V to 3.6V VCC I Power-off high impedance inputs and outputs I Supports live insertion and withdrawal (Note 1) I Static Drive (IOH /IOL ) ±12 mA @ 3.0V VCC I Uses patented noise/EMI reduction circuitry I Latch-up performance exceeds 300 mA I ESD performance: Human body model > 2000V Machine model > 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 “X” to the ordering code.

The device is byte controlled with each byte functioning identically, but independent of each other. The control pins may be shorted together to obtain full 20-bit operation. The 3-STATE outputs are controlled by Output Enable (OE n) inputs. When OE1, and OE2 are LOW, O 0–O 10 are in the 2-state mode. When either OE1 or OE 2 are HIGH, the standard outputs are in the high imped- ance mode but this does not interfere with entering new data into the inputs. The same applies for byte two with OE 3 and OE4.

3 www.fairchildsemi.com 74VCX162827 Absolute Maximum Ratings(Note 2) Recommended Operating Conditions (Note 4) Note 2: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. 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” table will define the condi- tions for actual device operation. Note 3: I O Absolute Maximum Rating must be observed. Note 4: Floating or unused inputs must be held HIGH or LOW.

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 ).
