SN74ALS832ADW

Overview

The SN74ALS832ADW is a hex 2-input OR gate manufactured by Texas Instruments, belonging to the Advanced Low-power Schottky (ALS) logic series. It features six independent OR gates with TTL-compatible inputs and standard totem-pole outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 9 ns, a low-level output current capability of 24 mA, and a high-level output current of -15 mA. It is housed in a 20-pin SOIC package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Hex configuration providing six independent 2-input OR logic functions
• Advanced Low-power Schottky technology for high-speed operation with reduced power consumption
• TTL-compatible input levels ensuring direct interface with other TTL devices
• Standard totem-pole output structure delivering robust drive capabilities

Applications

• Digital logic circuit design requiring multiple OR operations
• Signal routing and selection in bus systems
• Data processing units utilizing TTL-compatible logic families
• Industrial control systems operating within standard temperature ranges

Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-20 surface-mount package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the component meets the required industrial temperature range specifications for the intended application environment.

Selection Notes

Select this component when a hex OR gate configuration is required within ALS logic family constraints. Consider the 9 ns propagation delay and 24 mA sink current for timing and load requirements. Verify compatibility with existing TTL input standards and ensure the SOIC-20 package fits the PCB layout constraints compared to alternative DIP packages.

Part Context

This part belongs to the SN74ALS832A series of single-function logic gates. It is distinct from other ALS variants such as NAND or NOR gates by its specific OR logic function. The 'DW' suffix differentiates it from the 'AN' PDIP variant, indicating a surface-mount form factor suitable for automated assembly processes.

Replacement Considerations

Check for SN74ALS832AN if through-hole packaging is acceptable. Verify cross-brand equivalents from manufacturers like ON Semiconductor or Fairchild that match the ALS specification and pinout.
