10 Applications and Implementation
10.1 Application Information
The SN74LVC1G14 is a high drive CMOS device that can be used for a multitude of buffer type functions where
the input is slow or noisy. It can produce 24 mA of drive current at 3.3 V making it Ideal for driving multiple
outputs and good for high speed applications up to 100 MHz. The inputs are 5.5 V tolerant allowing it to translate
down to V_CC.
10.2 Typical Application

10.2.1 Design Requirements
This device uses CMOS technology and has balanced output drive. Care should be taken 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.
10.2.2 Detailed Design Procedure
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 (V_IH and V_IL) in the Recommended Operating Conditions table.
– Inputs are overvoltage tolerant allowing them to go as high as (V_I max) in the Recommended Operating
Conditions table at any valid V_CC .
2. Recommend Output Conditions
– Load currents should not exceed (I_O max) per output and should not exceed (continuous current through
V_CC or GND) total current for the part. These limits are located in the Absolute Max Ratings table.
– Outputs should not be pulled above V_CC.
