DM74150N

Overview

The DM74150N is a 16-line to 1-line data selector/multiplexer manufactured by onsemi (formerly Fairchild) in a 24-lead Plastic Dual-In-Line Package. It features full on-chip decoding for selecting one of sixteen data sources, controlled by four select inputs and an active-low strobe input. The device provides only an inverted W output. Recommended operating conditions specify a supply voltage range of 4.75V to 5.25V and an operating temperature range of 0°C to +70°C.

Feature Summary

• Selects one-of-sixteen data lines using full on-chip decoding
• Performs parallel-to-serial conversion and multiplexing from N lines to one line
• Functions as a Boolean function generator
• Includes an active-low strobe input that forces the W output HIGH when inactive

Applications

• Parallel-to-serial data conversion systems
• Multiplexing multiple signal lines into a single transmission path
• Implementation of complex Boolean logic functions

Procurement Notes

Verify component authenticity and datasheet revision status due to the device's age and potential discontinuation. Confirm package integrity and pin alignment against the 24-lead PDIP specification. Ensure compatibility with existing system voltage levels and thermal requirements before integration. Check for RoHS compliance if required by current manufacturing standards.

Selection Notes

Choose this component for applications requiring a single inverted output from sixteen selectable inputs. Verify that the TTL-compatible input voltage levels match the driving circuitry. Consider the propagation delay characteristics relative to system timing constraints. Evaluate power dissipation requirements within the specified operating temperature range.

Part Context

This part belongs to the standard 7400 series logic family, specifically designed for digital data routing and logic generation tasks. It utilizes bipolar transistor technology typical of its era. The device is distinct from non-inverting multiplexers by providing only the complemented output signal.

Replacement Considerations

Direct substitutes include other 16-to-1 multiplexers with inverted outputs such as the SN74150 or MC14516B. Verify pinout compatibility and electrical specifications before substitution.
