SN74ALS153DR

Overview

The SN74ALS153DR is a dual 1-of-4 data selector/multiplexer housed in a 16-pin Small Outline (D) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features two independent multiplexing sections with common select inputs A and B, allowing selection among four data inputs per section. Each section includes a separate strobe (enable) input for cascading or disabling outputs. The component utilizes Advanced Low-Power Schottky logic technology.

Feature Summary

• Contains two independent 1-of-4 multiplexers with shared binary decoding
• Features separate strobe inputs for each multiplexer section
• Supports parallel-to-serial conversion and signal routing
• Includes inverters and drivers for full binary decoding

Applications

• Multiplexing multiple signals to a single output line
• Parallel-to-serial data conversion circuits
• Cascaded n-line to n-line data routing systems
• Digital logic function implementation using data selectors

Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC package and tape-and-reel quantity of 2500 units. Confirm RoHS compliance status and lead finish details via the official Texas Instruments Package Option Addendum. Ensure the procurement channel sources from authorized distributors to guarantee authenticity and traceability for this catalog logic component.

Selection Notes

Select this component when designing systems requiring dual independent 4-input multiplexing within standard industrial temperature limits. Consider the ALS series characteristics for low power consumption relative to standard TTL. Verify that the required propagation delay and output drive current meet the system specifications under the intended load conditions and supply voltage variations.

Part Context

This part belongs to the Texas Instruments SN74ALS153 family of dual 1-of-4 data selectors. It is functionally compatible with other manufacturers' 74ALS153 equivalents but maintains specific electrical parameters defined by TI. The 'DR' suffix specifically denotes the plastic small-outline package variant supplied in large tape-and-reel format for automated assembly processes.

Replacement Considerations

The SN74AS153 serves as a higher-speed alternative within the same package footprint. Cross-reference with other 74ALS153 variants from different vendors only if electrical parameters such as propagation delay and output current are verified to be equivalent or superior.
