CD74HCT151E

Overview

The CD74HCT151E is a high-speed CMOS logic component functioning as an 8-input multiplexer. It features a single 8-to-1 data selector circuit housed in a 16-pin Dual In-line Package (PDIP). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -55°C to +125°C. It provides one true output and one complement output, ensuring signal integrity through complementary data paths.

Feature Summary

• High-speed CMOS technology for efficient digital signal routing
• Single 8-to-1 data selection capability with complementary outputs
• Wide industrial temperature range operation for robust performance

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor-based designs
• Waveform generation circuits

Procurement Notes

Verify the package type matches the required 16-pin DIP configuration. Confirm the HCT logic series compatibility with existing system voltage levels. Ensure the component meets RoHS standards if environmental compliance is mandatory for the specific application environment.

Selection Notes

Select this part when a single 8-channel multiplexer is required in a through-hole DIP package. The HCT series ensures TTL-compatible input thresholds while maintaining CMOS low power consumption. Verify that the 4.5V to 5.5V supply requirement aligns with the target system's power rails.

Part Context

This component belongs to the Texas Instruments CD74HCT151 family of high-speed CMOS logic devices. It serves as a standard 8-input multiplexer solution within the broader 74HCT logic portfolio, designed for applications requiring reliable data selection in industrial and commercial environments.

Replacement Considerations

Check for direct pin-compatible alternatives such as the CD74HC151E or other manufacturers' 74HCT151 equivalents. Ensure logical function and electrical characteristics match before substitution.
