CD74HC368E

Overview

The CD74HC368E is a high-speed CMOS logic hex buffer and line driver manufactured by Texas Instruments. It features six inverting buffers with three-state outputs, housed in a 16-pin PDIP package. The device operates within a supply voltage range of 2V to 6V, supporting a maximum frequency of 28MHz at nominal voltage. Key electrical characteristics include a maximum low-level output current of 6mA and a high-level output current of -6mA. Propagation delay is specified at 24ns at the nominal voltage. The component supports an operating temperature range from -55°C to 125°C and draws a maximum supply current of 0.08mA.

Feature Summary

• Integrates six independent inverting buffer channels for signal conditioning.
• Provides three-state output capability for bus-oriented applications.
• Utilizes high-speed CMOS technology for efficient power consumption.

Applications

• Bus-oriented systems requiring signal buffering
• Clock distribution networks
• Memory address decoding circuits

Procurement Notes

Verify the specific suffix 'E' corresponds to the PDIP-16 through-hole package configuration when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation, as environmental declarations may vary by production batch. Ensure the ordering part number matches the exact logical function and pinout requirements of the design specification before finalizing procurement.

Selection Notes

Select this component for designs requiring inverting logic with tri-state control in a through-hole format. Compare propagation delay specifications against system timing constraints to ensure signal integrity. Evaluate the 6mA drive capability against load requirements to determine if additional buffering is necessary for long traces or heavy capacitive loads.

Part Context

This device belongs to the CD74HC series of high-speed CMOS logic products. It serves as the inverting counterpart to the non-inverting CD74HC367. Both devices share similar electrical characteristics and packaging options, differing primarily in logical polarity. The series is designed for compatibility with standard CMOS logic families while offering improved speed over older technologies.

Replacement Considerations

The SN74HC368N is a direct functional equivalent in a DIP package. For surface mount applications, the CD74HC368MT provides identical logical functionality in an SOIC-16 package. Verify pin compatibility and electrical parameters when substituting these alternatives.
