Output Type Selection Guide

Output Type Advantages Disadvantages
Fixed Voltage (TTL/CMOS) No additional components.
Known output voltage.
Signal degradation with difficult loads.
More susceptible to line noise.
Supply Tracking No additional components.
Supply voltage can be tracked.
Low cost.
Signal degradation with difficult loads.
More susceptible to line noise.
Output varies with supply voltage.
Open Collector Different supply and output voltages.
Optimize drive current by pull up resistor selection.
Requires additional pull up resistor. See Open Collector Pullup Resistor Calculator.
More susceptible to line noise.
Single Ended Push-Pull Fixed Voltage No additional components.
Known output voltage.
Improved signal integrity with difficult loads. Thermal and show circuit protection.
Moderate line noise immunity.
Single Ended Push-Pull Supply Tracking No additional components.
Supply voltage can be tracked.
Improved signal integrity with difficult loads.
Moderate line noise immunity.
Output varies with supply voltage.
Thermal and short circuit protection.
Differential Push-Pull, Fixed or Supply Tracking High noise tolerance when paired with and impedance matched differential receiver. Requires two connections for each output.
Higher cost.
