9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
9.1 Application Information
The SN74LVC2G32 device is dual 2-input OR gate. High-output current capability is ideal for driving multiple outputs.
9.2 Typical Application
3-input OR configuration, Y = A + B + C
Figure 4. 3-input OR gate
9.2.1 Design Requirements
This device uses CMOS technology and has balanced output drive. Take care to avoid bus contention because it can drive currents that would exceed maximum limits. Outputs can be combined to produce higher drive but the high drive will also create faster edges into light loads so routing and load conditions should be considered to prevent ringing.
9.2.2 Detailed Design Procedure
- Recommended Input Conditions:
- For rise time and fall time specifications, see (Δt/ΔV) in Recommended Operating Conditions table.
- For specified high and low levels, see (VIH and VIL) in Recommended Operating Conditions table.
- Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC.
- Recommend Output Conditions:
- Load currents should not exceed 50 mA per output and 100 mA total for the part.
- Series resistors on the output may be used if the user desires to slow the output edge signal or limit the output current.
