SYMBOL tPHL/tPLH PARAMETER propagation delay CP to Q 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 µW). PD = CPD × VCC2 × fi × N + (CL × VCC2 × 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; (CL × VCC2 × fo) = sum of the outputs. 2. The condition is VI = GND to VCC. input capacitance power dissipation capacitance per buffer VCC = 3.3 V; notes 1 and 2 DESCRIPTION
74LVC1G79
The 74LVC1G79 is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 or 5 V devices. This feature allows the use of this device in a mixed 3.3 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 74LVC1G79 provides a single positive-edge triggered D-type flip-flop. Information on the data input is transferred to the Q output on the LOW-to-HIGH transition of the clock pulse. The D input must be stable one set-up time prior to the LOW-to-HIGH clock transition for predictable operation.
