Frequently Asked Questions

What does 74LS mean?

74LS stands for '74-series Low-power Schottky.' The '74' indicates a commercial-grade TTL logic family, while 'LS' denotes Low-power Schottky technology. LS devices use Schottky transistors to reduce power consumption while maintaining good switching speed compared to standard 74-series TTL, making them widely used in digital glue logic and bus interfacing applications.
