4 / 8 page DC Electrical Characteristics for ’ACTQ Family Devices (Continued) 54ACTQ Symbol Parameter V CC T A = Units Conditions (V) −55˚C to +125˚C Guaranteed Limits I CC Maximum Quiescent 5.5 160.0 µA V IN = VCC Supply Current or GND (Note 5) V OLP Quiet Output 5.0 V (Notes 6, 7) Maximum Dynamic V OL V OLV Quiet Output 5.0 V (Notes 6, 7) Minimum Dynamic V OL Note 3: All outputs loaded; thresholds on input associated with output under test. 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: Plastic DIP package. Note 7: Max number of outputs defined as (n). Data inputs are driven 0V to 3V. One output @ GND. Note 8: Maximum number of data inputs (n) switching. (n−1) inputs switching 0V to 3V (’ACTQ). Input-under-test switching: 3V to threshold (VILD), 0V to threshold (VIHD), f = 1 MHz. AC Electrical Characteristics 54ACTQ V CC T A = −55˚C Fig. Symbol Parameter (V) to +125˚C Units No. (Note 9) C L = 50 pF Min Max f max Maximum Clock 5.0 95 MHz Frequency t PLH, Propagation Delay 5.0 2.5 11.5 ns t PHL CP to O n t PZH, Output Enable Time 5.0 2.5 13.0 ns t PZL OE to O n t PHZ, Output Disable Time 5.0 1.0 9.0 ns t PLZ OE to O n Note 9: Voltage Range 5.0 is 5.0V ±0.5V Note 10: 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.
