QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C. SYMBOL tPHL/tPLH PARAMETER CONDITIONS VCC = 2.5 V; CL = 30 pF; RL = 500 VCC = 2.7 V; CL = 50 pF; RL = 500 VCC = 3.3 V; CL = 50 pF; RL = 500 VCC = 5.0 V; CL = 50 pF; RL = 500 CI CPD input capacitance power dissipation capacitance per buffer output enabled; notes 1 and 2 output disabled; notes 1 and 2 Notes 1. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x 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 load switching outputs; (CL x VCC2 x fo) = sum of outputs. 2. The condition is VI = GND to VCC. DESCRIPTION
74LVC2G125
The 74LVC2G125 is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators 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 74LVC2G125 provides a dual non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by the output enable input (pin nOE). A HIGH-level at pin nOE causes the output to assume a high-impedance OFF-state. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times.
