DM74153N

Overview

The DM74153N is a dual 4-line to 1-line data selector/multiplexer manufactured by National Semiconductor. It operates on a single supply voltage ranging from 4.75V to 5.25V and supports an operating temperature range of 0°C to 70°C. The component utilizes through-hole mounting technology and features independent circuits within a single package, designed for digital logic applications requiring signal routing.

Feature Summary

• Dual independent multiplexing channels
• Standard TTL-compatible operation
• Through-hole DIP packaging

Applications

• Digital logic systems
• Industrial controls
• Professional electronics

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, as ownership transitions occurred. Confirm the suffix 'N' indicates the specific through-hole DIP package variant. Ensure the device meets RoHS compliance requirements if mandated by your project specifications. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required in standard TTL environments. It is suitable for designs needing separate signal paths without cross-interference between channels. Consider the through-hole form factor for prototyping or legacy board layouts where surface-mount alternatives are not viable.

Part Context

This part belongs to the 74153 family of dual 4-line to 1-line data selectors. It is functionally equivalent to other manufacturers' 74153 variants but carries the National Semiconductor prefix. The device serves as a fundamental building block for data routing in digital circuits, offering two complete multiplexer units in one package.

Replacement Considerations

Public confirmed substitute part numbers include DM54153W. Verify pin compatibility before substitution.
