Product Description:

The SN74LS253N is a representative of the 74LS logic family, which ensures compatibility with a wide range of digital systems. This device provides two individual 4-line to 1-line selectors/multiplexers with a common binary address input (A, B). It allows the selection of one of four data sources for each multiplexer by the address lines. Moreover, the 3-state outputs can deliver the selected data without interference when enabled or remain in a high-impedance state when disabled, allowing for the use in bus-oriented systems.

Thanks to its standard PDIP-16 packaging, the SN74LS253N is easy to handle and integrate into various circuit boards. The chip operates within a supply voltage range of 4.75V to 5.25V, which is typical for TTL logic levels, and it features a low power consumption. The propagation delay time is relatively short, ensuring quick data selection and minimal signal latency.

Whether used in digital multiplexing, data routing, or signal gating, the SN74LS253N's robust design and functionality make it a go-to choice for engineers and electronics enthusiasts alike. With Texas Instruments' commitment to quality, this product is a reliable and efficient solution for complex digital systems.
