9 / 28 page GND VCC 0.1 F From MCU 1A 2A 1Y 2Y SN74LVC2G07 www.ti.com SCES308L – AUGUST 2001 – REVISED MAY 2015 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 SN74LVC2G07 is a high-drive CMOS device that can be used to implement a high output drive buffer, such as an LED application. It can sink 32 mA of current at 4.5 V making it ideal for high-drive and wired-OR/AND functions. The inputs are 5.5 V tolerant allowing it to translate up and down to VCC. 9.2 Typical Application Figure 3. Typical Application 9.2.1 Design Requirements 1. Recommended Input Conditions – Rise time and fall time specs. See ( Δt/ΔV) in the Recommended Operating Conditions table. – Specified high and low levels. See (VIH and VIL) in the Recommended Operating Conditions table. – Inputs are overvoltage tolerant allowing them to go as high as (VI max) in the Recommended Operating Conditions table at any valid VCC. 2. Recommend Output Conditions – Load currents should not exceed (IO max) per output and should not exceed (Continuous current through VCC or GND) total current for the part. These limits are located in the Absolute Maximum Ratings table. – Outputs should not be pulled above 5.5 V. 9.2.2 Detailed Design Procedure 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. The high drive will also create fast edges into light loads so routing and load conditions should be considered to prevent ringing.
