DM74S151N

Overview

The DM74S151N is a 1-of-8 data selector/multiplexer with complementary outputs, manufactured by onsemi. It operates within a supply voltage range of 4.75V to 5.25V and features a typical average propagation delay of 4.5ns from data input to the W output. The device dissipates approximately 225mW of power under standard conditions. It utilizes a 16-lead plastic dual-in-line package (PDIP) suitable for through-hole mounting.

Feature Summary

• Selects one of eight data lines using full on-chip decoding
• Provides complementary W and Y outputs for signal routing
• Includes a strobe input that disables the device when set high

Applications

• Parallel-to-serial data conversion
• Multiplexing multiple lines into a single line
• Boolean function generation

Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the 16-lead PDIP package as documented in the official datasheet. Confirm that the component meets the required operating temperature range of 0°C to +70°C for your intended environment. Ensure compatibility with the specified TTL logic levels before integration.

Selection Notes

This component is designed for applications requiring fast switching speeds and parallel-to-serial conversion capabilities. Consider the 225mW power dissipation and the need for a low-level strobe signal during operation. The complementary outputs allow for flexible circuit design without additional inversion stages.

Part Context

The DM74S151 belongs to the 74S series of logic integrated circuits, characterized by Schottky technology for high-speed performance. This specific model functions as an 8-channel multiplexer, providing both true and inverted outputs to support complex digital logic requirements in industrial and commercial systems.

Replacement Considerations

Direct substitutes include the SN74LS51N from Texas Instruments, which offers similar functionality. Verify pinout compatibility and electrical characteristics against the original specifications before swapping components.
