BUFFERS WITH OPEN-DRAIN
OUTPUTS
DESCRIPTION
The U74LVC2G07 provides two non-inverting buffers with
open-drain output and can be connected to other open-drain
outputs to implement active-LOW wired-OR or active-HIGH
wired-AND functions.
This device has power-down protective circuit to preventing
device from destruction when it is powered down.
FEATURES
* Wide Supply Voltage Range From 1.65V To 5.5V.
* Inputs Can Be Driven From Either 3.3V or 5V Devices.
* Low Power Dissipation: Ptot =300mW(Max)
* -24mA Output Drive(VCC=3.0V)
* Power Down Protection
* Latch-Up Performance Exceeds 250mA.
* High Noise Immunity
* Direct Interface With TTL Levels

Note: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
3. When VCC =0V(Power-Down Mode),the output voltage can be 5.5V in normal operation.

PD is used to determine the dynamic power dissipation (PD in µW).
Notes: 1.
PD = CPD * Vcc2 * fi * N + Σ（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 Load Switching Outputs.
Σ(CL * Vcc2 * fo)= Sum of Outputs.
The Condition is VIN = GND to Vcc.
