Overview
The SN74ALS352D is a dual 4-line to 1-line data selector/multiplexer from Texas Instruments' Advanced Schottky (ALS) logic family. It integrates two independent multiplexers within a single SOIC-16 package, designed for high-speed digital signal routing applications. The device operates with a supply voltage range of 4.5 V to 5.5 V and features low power consumption characteristic of the ALS series. It provides efficient data selection capabilities for system architectures requiring multiple input channels.
Feature Summary
- Dual independent 4-to-1 multiplexer configuration
- Advanced Schottky technology for high-speed operation
- Standard TTL-compatible logic levels
Applications
- Data routing in digital communication systems
- Address decoding circuits
- Signal switching in test equipment
Procurement Notes
Verify the specific suffix 'D' indicates the SOIC-16 surface-mount package variant. Confirm the manufacturer is Texas Instruments to ensure compatibility with ALS series specifications. Check for RoHS compliance status if required by your assembly process. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.
Selection Notes
Select this component when dual independent 4-channel multiplexing is required in a compact surface-mount format. The ALS series offers a balance of speed and power dissipation suitable for general-purpose digital logic. Consider the SOIC-16 footprint constraints during PCB layout. Verify that the 4.5 V to 5.5 V operating range aligns with your system's power supply design.
Part Context
This part belongs to the Texas Instruments SN74ALSxx series, which utilizes Advanced Schottky bipolar technology. This family is known for improved speed-power product compared to standard LS logic. The SN74ALS352D specifically addresses needs for multi-channel data selection without requiring multiple discrete components.
Replacement Considerations
Compatible substitutes include other SN74ALS352 variants or equivalent dual 4-to-1 multiplexers from the same logic family. Ensure pinout compatibility and identical electrical characteristics such as propagation delay and supply voltage range before substitution.
