SN74LS251N Description

Short technical summary and product information.

The SN74LS251N from Texas Instruments is a monolithic data selector/multiplexer featuring on-chip binary decoding to select one of eight data sources. It has a strobe-controlled three-state output, which must be at a low logic level to enable the device. This feature allows multiple outputs to be connected to a common bus.

 

Key electrical specifications include an operating voltage range of 4.75V to 5.25V and an operating temperature range of 0°C to 70°C. The circuit configuration is 1 x 8:1, with one independent circuit. Current specifications are 2.6mA and 8mA.

 

Packaged in a 16-PDIP through-hole component, the SN74LS251N is designed for direct interface with system buses and can perform parallel-to-serial conversion. It is fully compatible with most TTL circuits. The device is suitable for applications requiring multiplexing from multiple data lines to a single output line.
