DM74ALS258M

The DM74ALS258M from ON Semiconductor is a Quad 1-of-2-Line Data Selector/Multiplexer. This integrated circuit is designed to route a 4-bit word from one of two sources to four 3-STATE outputs, enabling direct interface with data lines of bus-organized systems. It operates with a single supply voltage ranging from 4.5V to 5.5V and functions within an ambient temperature range of 0°C to 70°C.

The device utilizes an advanced Schottky TTL process, offering improved AC performance compared to its predecessors. The 3-STATE buffer-type outputs are capable of driving bus lines directly, facilitating the implementation of n-bit data selectors for data buses. It also supports the use of standard TTL registers for data retention.

The DM74ALS258M is housed in a 16-SOIC package with surface mount mounting type. Its circuit configuration is 4 x 2:1, with one independent circuit. The typical current consumption is 2.6mA, with a maximum of 24mA.

This multiplexer is suitable for applications requiring data selection and routing in digital systems, including expanding data input points and multiplexing dual data buses.
