The SN74AS757, manufactured by Texas Instruments, is a high-performance, dual 2-to-4 line decoder/demultiplexer designed to provide efficient and reliable service in a wide range of digital applications. This integrated circuit is part of TI's Advanced Schottky (AS) family, known for its fast switching speeds and low power consumption, making it an ideal choice for high-speed memory decoders, data transmission systems, and various other digital logic applications.
Key Features
- Logic Family: Advanced Schottky (AS)
- Operating Voltage: Typically 5V
- High-Speed: Fast propagation delay times
- Low Power Consumption: Reduced power usage compared to traditional Schottky devices
- Output Drive Capability: Capable of driving 15 LS-TTL loads

Functional Description
The SN74AS757 features two individual 2-to-4 decoders, each with its own address inputs (A0, A1), an enable input (E), and four mutually exclusive outputs (O0 to O3). When the enable input is high, all outputs are low. When the enable input is low, one of the four outputs will go high based on the combination of the address inputs. This enables the device to decode a two-bit binary input into one of four active outputs, effectively demultiplexing the input signal.
Applications
The flexibility and speed of the SN74AS757 make it a versatile component suitable for a variety of applications, including:
- Data routing
- Memory address decoding
- Control signal generation
- Demultiplexing for data acquisition systems
- Interface circuitry
