The NTE74LS353 is a dual 4-to-1 line data selector/multiplexer with 3-state outputs. It is part of the 74LS series of TTL (Transistor-Transistor Logic) integrated circuits and is manufactured by NTE Electronics. This device selects one of four data sources on each of its two multiplexer sections based on the select inputs, and outputs the selected data. The 3-state outputs allow the device to be connected to a bus without interfering with other devices when not enabled.

Additional Details

The NTE74LS353 is commonly used in digital logic circuits where data selection or multiplexing is required. The select inputs determine which of the four data inputs is routed to the output. The 3-state outputs are controlled by an enable input, which allows the output to be disabled, placing it in a high-impedance state. This feature is useful when multiple devices are connected to a common bus. The device operates with a supply voltage of 5V, typical for TTL logic. Detailed specifications, including propagation delays, power consumption, and pin configurations, are available in the NTE Electronics datasheet for the NTE74LS353. This multiplexer offers a reliable and versatile solution for data selection in a wide range of digital applications.
