What is the standard TTL output current?

The standard TTL (Transistor-Transistor Logic) output current typically is 16 mA. This current level ensures that TTL circuits can reliably drive loads, such as input terminals of other TTL devices or low-power relay coils, without risking damage to the components.

Driving the output at this specified current allows for adequate switching speed while maintaining the integrity of the signal. This current specification is crucial in practical applications as it influences the design and interoperability of digital circuits in various configurations. The 16 mA output ensures compatibility with devices designed to operate within these electrical characteristics.
