CD74HC157E

Overview

The CD74HC157E is a quad 2-input multiplexer manufactured by Harris Corporation. It belongs to the 74HC logic family and utilizes CMOS technology. The device features four independent data selectors that route one of two input sources to a common output based on a shared select line. It operates within a supply voltage range of 2V to 6V and supports through-hole mounting in a 16-pin DIP package. The component is designed for high-speed digital signal routing applications.

Feature Summary

• Provides four independent 2-to-1 data selection channels
• Utilizes a common select input to control all channels simultaneously
• Outputs true (non-inverted) data signals
• Compatible with standard TTL logic levels

Applications

• Routing data between multiple registers to a common bus
• Function generator circuit implementations
• Digital signal path switching in instrumentation

Procurement Notes

Verify the manufacturer designation carefully, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Confirm whether the specific unit is an original Harris production or a subsequent Renesas release under the same part number. Ensure the package type matches the required 16-DIP specification for your design.

Selection Notes

Select this component when a quad multiplexer with true outputs is required. Note that the CD74HC158 offers identical functionality but provides inverted outputs. Verify that the operating voltage range of 2V to 6V aligns with the system power supply requirements before finalizing the design.

Part Context

This component is part of the 74HC series of high-speed CMOS logic devices. It serves as a functional equivalent to other industry-standard quad multiplexers. The device is widely used in digital systems requiring efficient data routing and signal management across multiple channels.
