7 / 10 page 7 www.fairchildsemi.com AC Electrical Characteristics for ACTQ Note 16: Voltage Range 5.0 is 5.0V ±0.5V Note 17: 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. Note 18: These delay times reflect the 3-STATE recovery time only and not the signal time through the buffers or the parity check circuitry. To assure VALID information at the ERROR pin, time must be allowed for the signal to propagate through the drivers (B to A), through the parity check circuitry (same as A to PARITY), and to the ERROR output after the ERROR pin has been enabled (Output Enable times). VALID data at the ERROR pin ≥ (A to PARITY) + (Output Enable Time).
