6 / 8 page www.fairchildsemi.com 6 AC Electrical Characteristics Note 9: 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). Capacitance (Note 10) Note 10: Capacitance is measured at frequency f = 1 MHz, per MIL-STD-883B, Method 3012. Symbol Parameter TA = −40°C to +85°C Units CL = 50 pF, RL = 500 Ω VCC = 3.3 ± 0.3V VCC = 2.7V MinMax MinMax tPLH Propagation Delay 1.2 4.2 1.2 4.5 ns tPHL Data to Outputs 1.2 4.4 1.2 4.9 tPLH Propagation Delay 1.3 4.7 1.3 5.5 ns tPHL LE to A or B 1.3 5.1 1.3 5.8 tPZH Output Enable Time 1.3 4.7 1.3 5.4 ns tPZL OE to A or B 1.3 5.1 1.3 6.1 tPHZ Output Disable Time 2.0 5.5 2.0 5.7 ns tPLZ OE to A or B 2.0 4.9 2.0 4.9 tPZH Output Enable Time 1.3 4.6 1.3 5.6 ns tPZL CE to A or B 1.3 5.0 1.3 6.1 tPHZ Output Disable Time 2.0 5.5 2.0 5.8 ns tPLZ CE to A or B 2.0 4.9 2.0 4.9 tW Pulse Duration LE LOW 3.3 3.3 ns tS Setup Time A or B before LE, Data HIGH 0.5 0.5 ns A or B before LE, Data LOW 0.8 1.3 A or B before CE, Data HIGH 0.5 0.0 A or B before CE, Data LOW 0.6 1.1 tH Hold Time A or B after LE, Data HIGH 1.5 0.7 ns A or B after LE, Data LOW 1.2 1.3 A or B after CE, Data HIGH 1.7 0.9 A or B after CE, Data LOW 1.6 1.8 tOSLH Output to Output Skew (Note 9) 1.0 1.0 ns tOSHL 1.0 1.0 Symbol Parameter Conditions Typical Units CIN Input Capacitance VCC = OPEN, VI = 0V or VCC 4pF CI/O Input/Output Capacitance VCC = 3.0V, VO = 0V or VCC 8pF |
