Note 4: Maximum test duration 2.0 ms, one output loaded at a time. Note 5: ICC for 54ACTQ @ 25˚C is identical to 74ACTQ @ 25˚C. Note 6: Max number of outputs defined as (n). Data inputs are driven 0V to 3V. One output @ GND. AC Electrical Characteristics 54ACTQ V CC T A = −55˚C Fig. Symbol Parameter (V) to +125˚C Units No. (Note 7) C L = 50 pF Min Max t PLH, Propagation Delay 5.0 2.0 9.5 ns Figure 4 t PHL D n to On 2.0 11.0 t PLH, Propagation Delay 5.0 2.0 11.0 ns Figure 4 t PHL LE to O n 2.0 11.0 t PZH, Output Enable Time 5.0 1.5 11.0 ns Figure 5 t PZL OE to O n 1.5 13.0 t PHZ, Output Disable Time 5.0 1.5 8.5 ns Figure 5 t PLZ OE to O n 1.5 5.5 Note 7: Voltage Range 5.0 is 5.0V ±0.5V. Note 8: Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs within the same packaged device. The specification applies to any outputs switching in the same direction, either HIGH to LOW (tOSHL) or LOW to HIGH (tOSLH). Parameter guaranteed by design. Not tested.
