MC74HC368N

Overview

The MC74HC368N is a dual bus driver manufactured by onsemi, belonging to the HC/UH logic series. It features two independent functions, each handling four bits of data with inverted outputs. The device utilizes CMOS technology and is housed in a PDIP-16 plastic package. It operates within a supply voltage range of 2.0 V to 6.0 V. Key electrical characteristics include a maximum low-level output current of 9 mA and a load capacitance specification of 50 pF. The component supports surface mount and through-hole installation styles.

Feature Summary

• Provides dual independent four-bit bus driving capability with inverted outputs for signal buffering
• CMOS construction ensures high noise immunity and low input current consumption
• Outputs are directly compatible with standard CMOS, NMOS, and TTL loads

Applications

• Memory address decoding circuits
• Clock distribution buffers
• Carry propagation in arithmetic logic units

Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-16 package configuration. Confirm RoHS compliance status as historical variants may differ. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or speed grade discrepancies. Cross-reference the datasheet revision date against your design requirements.

Selection Notes

Select this component when dual buffered inversion is required for bus lines. The HC series offers a wide voltage operating range suitable for various digital systems. Consider the PDIP-16 package only if through-hole mounting is necessary for the mechanical assembly constraints.

Part Context

This device is part of the industry-standard 74HC logic family, designed for high-speed CMOS operations. It serves as a direct replacement for older LS-series drivers in many applications while offering improved power efficiency. The dual-function architecture allows for efficient space utilization in compact digital designs requiring signal isolation or level shifting.

Replacement Considerations

Compatible substitutes include SN74HC368 from Texas Instruments and MC74HC368ADJR2G from onsemi in alternative packages. Verify that substitute parts maintain the same inverted output polarity and PDIP-16 footprint if physical compatibility is required.
