QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C. SYMBOL tPZL/tPLZ PARAMETER propagation delay inputs nA and nB to output nY CONDITIONS VCC = 1.8 V; CL = 30 pF; RL = 1 k 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 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 = number of inputs switching; (CL x VCC2 x fo) = sum of outputs. 2. The condition is VI = GND to VCC. input capacitance power dissipation capacitance per gate VCC = 3.3 V; notes 1 and 2 DESCRIPTION
74LVC2G38
The 74LVC2G38 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. These 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 74LVC2G38 provides the 2-input NAND function. The outputs of the 74LVC2G38 devices are open drain and can be connected to other open-drain outputs to implement active-LOW, wired-OR or active-HIGH wired-AND functions.
