The SN74ALS253DRG4 is a high-quality, dual 1-of-4 line data selector/multiplexer designed and manufactured by Texas Instruments. This integrated circuit is part of the advanced low-power Schottky (ALS) logic family, which combines the speed of Schottky TTL with the low power consumption of standard TTL circuits.

The SN74ALS253DRG4 features two individual 1-of-4 multiplexers with common select inputs and individual enable inputs. Each multiplexer has four binary inputs (A0 to A3 and B0 to B3), two select inputs (S0 and S1), an enable input (E), and one output (Y). The device allows data from any of the four binary inputs to be routed to the output, depending on the state of the select and enable inputs.

Key Features:

• Logic Family: Advanced Low-Power Schottky (ALS)
• Operating Voltage Range: 4.5V to 5.5V, which is ideal for 5V systems.
• High-Speed Performance: Typical propagation delay time of 4.5 ns, providing fast switching for high-frequency applications.
• Low Power Consumption: The ALS technology ensures reduced power usage without compromising speed.
• Package Type: The device comes in an SOIC-16 package, which is suitable for surface-mount technology (SMT).
• Multiple Configuration Options: Dual 1-of-4 configuration allows for flexible use in various digital circuits.

Applications:

The SN74ALS253DRG4 is a versatile component used in a wide range of applications, including:

• Data routing
• Signal gating
• Function generation
