10 / 17 page Electrical characteristics 54VCXH162373 10/17 Table 8. AC electrical characteristics (CL = 30pF, RL = 500Ω, Input tr = tf = 2.0ns) Symbol Parameter Test condition Value Unit VCC (V) -55 to 125 °C Min Max tPLH tPHL Propagation delay time Dn to Qn 2.3 to 2.7 1.0 5.2 ns 3.0 to 3.6 0.8 4.0 tPLH tPHL Propagation delay time LE to Qn 2.3 to 2.7 1.0 5.7 ns 3.0 to 3.6 0.8 4.2 tPZL tPZH Output enable time 2.3 to 2.7 1.0 6.2 ns 3.0 to 3.6 0.8 4.7 tPLZ tPHZ Output disable time 2.3 to 2.7 1.0 5.1 ns 3.0 to 3.6 0.8 4.8 ts Setup tIme, HIGH or LOW level Dn to LE 2.3 to 2.7 1.0 ns 3.0 to 3.6 1.0 th Hold time HIGH or LOW level Dn to LE 2.3 to 2.7 1.5 ns 3.0 to 3.6 1.5 tw LE pulse width, HIGH 2.3 to 2.7 1.5 ns 3.0 to 3.6 1.5 tOSLH tOSHL Output to output skew time (1) (2) 1. Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switching in the same direction, either HIGH or LOW (tOSLH = | tPLHm - tPLHn|, tOSHL = | tPHLm - tPHLn|) 2. Parameter guaranteed by design 2.3 to 2.7 0.5 ns 3.0 to 3.6 0.5 Table 9. Capacitive characteristics Symbol Parameter Test condition Value Unit VCC (V) TA = 25 °C Min Typ Max CIN Input capacitance 2.5 or 3.3 VIN = 0 or VCC 6pF COUT Output capacitance 2.5 or 3.3 VIN = 0 or VCC 7pF CPD Power dissipation capacitance (1) 1. CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/16 (per circuit) 2.5 or 3.3 fIN = 10MHz VIN = 0 or VCC 20 pF |
