DESCRIPTION The 74LVC1G125 is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. The input can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device in a mixed 3.3 V and 5 V environment. This device is fully specified for partial power-down applications using Ioff. The Ioff circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. The 74LVC1G125 provides one non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by the output enable input (OE). A HIGH level at pin OE causes the output to assume a high-impedance OFF-state. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf £ 2.5 ns. Notes 1. CPD is used to determine the dynamic power dissipation (PD in mW). PD = CPD ´ VCC 2 ´ fi ´ N + S(CL ´ VCC 2 ´ fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total switching outputs; S(CL ´ VCC 2 ´ fo) = sum of the outputs. 2. The condition is VI = GND to VCC. SYMBOL PARAMETER CONDITIONS TYPICAL UNIT tPHL/tPLH propagation delay input A to output Y V
