CD74HC241E

Overview

The CD74HC241E is an 8-bit bus driver and transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V, supporting standard HC-CMOS logic levels. The device features dual 4-bit configurations with three-state outputs, allowing for effective bus management in digital systems. It utilizes a 20-pin Dual In-line Package (DIP) construction, suitable for through-hole mounting on printed circuit boards. The component is designed for high-speed applications, offering reliable signal transmission across various industrial and commercial electronic environments.

Feature Summary

• Provides dual 4-bit non-inverting buffer functionality with three-state output control
• Supports bidirectional data transfer when configured as a bus transceiver
• Operates reliably across a wide DC power supply voltage range from 2 V to 6 V

Applications

• Bus-oriented memory and register implementations
• Clock drivers and buffered oscillators
• Bidirectional bus transceivers in communication interfaces

Procurement Notes

Verify the package type matches the required DIP-20 configuration before procurement. Confirm that the manufacturer designation aligns with Texas Instruments specifications, as other vendors may produce equivalent parts under similar designations. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process. Cross-reference the specific ordering suffix to guarantee compatibility with existing inventory standards.

Selection Notes

Select this component when a dual 4-bit buffer or transceiver with three-state outputs is required for bus architectures. Consider the 2 V to 6 V operating range for compatibility with varying logic levels. Evaluate the DIP-20 package constraints against available board space and mounting preferences. Compare propagation delay characteristics against system timing requirements to ensure signal integrity is maintained during high-speed operations.

Part Context

This part belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. The 74HC family is widely recognized for its compatibility with standard TTL logic inputs while offering lower power consumption than older LS technologies. The CD74HC241 specifically addresses the need for isolated, controlled data flow in complex digital circuits requiring multiple independent channels.

Replacement Considerations

Equivalent parts include the SN74HC241N and generic 74HC241 variants from other manufacturers. Verify pinout compatibility and electrical parameters such as output drive current and propagation delay before substitution.
