SN74HC251DR Description

Short technical summary and product information.

The SN74HC251DR is a data selector/multiplexer IC manufactured by Texas Instruments. It features a 1-of-8 data selection capability with strobe-controlled complementary 3-state outputs, making it suitable for parallel-to-serial conversion.

 

This device operates within a wide voltage range of 2V to 6V and offers high-current 3-state outputs that can interface directly with system buses or drive up to 15 LSTTL loads. It exhibits low power consumption with a maximum ICC of 80 μA and a typical propagation delay of 9 ns. The output drive capability is ±6 mA at 5V, and the input current is a low 1 μA maximum.

 

The SN74HC251DR is available in a 16-SOIC package, designed for surface mounting. Its operating temperature range is -40°C to 85°C, making it suitable for various industrial applications. The complementary outputs provide both true and inverted data signals.

 

This multiplexer is a 3-state version of the 'HC151, offering flexibility in digital system design. Its configuration allows for efficient data routing and selection in complex logic circuits.
