The SN74HC251D is a data selector/multiplexer IC manufactured by Texas Instruments. It is designed to select one of eight data sources and features strobe-controlled complementary 3-state outputs. This device operates over a wide voltage range of 2V to 6V, making it suitable for various applications.
The SN74HC251D comes in a 16-SOIC package with a surface mount type, facilitating easy integration into printed circuit boards. Its operating temperature range is -40°C to 85°C, ensuring reliable performance in different environmental conditions. Key electrical characteristics include a typical propagation delay of 9 ns and low power consumption.
This multiplexer performs parallel-to-serial conversion and provides complementary outputs. The high-current 3-state outputs can interface directly with system buses or drive up to 15 LSTTL loads. Its low input current and wide operating voltage range contribute to its versatility in digital circuit designs.
