The DM74LS251N from On Semiconductor is a 3-STATE 1-of-8 line data selector/multiplexer. This integrated circuit features full on-chip binary decoding to select one of eight data sources and provides a strobe-controlled 3-STATE output, allowing direct connection to a common bus. The device operates with a single supply voltage ranging from 4.75V to 5.25V and is designed for a temperature range of 0°C to 70°C.
Key electrical characteristics include a typical propagation delay time (D to Y) of 17 ns and a typical power dissipation of 35 mW. The DM74LS251N is available in a 16-PDIP package, suitable for through-hole mounting. Its 3-STATE outputs enable efficient bus interfacing and parallel-to-serial conversion capabilities.
This multiplexer is a 3-STATE version of the DM74LS151 and offers complementary outputs for true and inverted data. The output control circuitry is designed to minimize the possibility of two outputs attempting to drive a common bus to opposite logic levels, with the average output disable time being shorter than the average output enable time.
