MC74LVX125 Quad Bus Buffer With 5 V−Tolerant Inputs The MC74LVX125 is an advanced high speed CMOS quad bus buffer. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems. The MC74LVX125 requires the 3−state control input (OE) to be set High to place the output into the high impedance state. http://onsemi.com Features • • • • • • • • • High Speed: tPD = 4.4 ns (Typ) at VCC = 3.3 V Low Power Dissipation: ICC = 4 mA (Max) at TA = 25°C Power Down Protection Provided on Inputs Balanced Propagation Delays Low Noise: VOLP = 0.5 V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300 mA Human Body Model > 2000 V Machine Model > 200 V These Devices are Pb−Free and are RoHS Compliant SOIC−14 NB D SUFFIX CASE 751A TSSOP−14 DT SUFFIX CASE 948G PIN ASSIGNMENT VCC OE3 D3 O3 OE2 D2 14 11 13 12 10 9 O2 8 ESD Performance: 1 OE0 OE2 2 D0 3 O0 D2 4 OE1 OE3 5 D1 6 O1 D3 1 2 OE0 D0 10 9 6 7 O1 GND 14−Lead (Top View) 8 O2 13 12 3 4 5 O0 OE1 D1 11 MARKING DIAGRAMS 14 O3 LVX125G AWLYWW Figure 1.

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); parameter guaranteed by design.

CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC / 4 (per bit). CPD is used to determine the no−load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
