74LVC1G07
Buffer with open-drain output
Rev. 08 — 17 July 2007
Product data sheet
1. General description
The 74LVC1G07 provides the non-inverting buffer.
The output of this device is an open drain and can be connected to other open-drain
outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions.
Inputs 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.
Schmitt-trigger action at all inputs makes the circuit tolerant for slower input rise and fall
time.
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 minimum input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2]
When VCC = 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
[3]
For TSSOP5 and SC-74A packages: above 87.5 °C the value of Ptot derates linearly with 4.0 mW/K.
For XSON6 packages: above 45 °C the value of Ptot derates linearly with 2.4 mW/K.

[2]
tpd is the same as tPLZ and tPZL.
[3]
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 V;
N = number of inputs switching;
∑(CL × VCC2 × fo) = sum of outputs.
