CD74HC367E

Overview

The CD74HC367E is a high-speed CMOS logic hex buffer and line driver featuring non-inverting three-state outputs. It operates within a supply voltage range of 2 V to 6 V, with a nominal voltage of 5 V. The device provides an output drive capability of ±6 mA at 5 V and exhibits a typical propagation delay of 10 ns. It functions as a dual four-line and two-line buffer/driver controlled by low-active output enable inputs (1OE and 2OE). When enabled, data passes from input to output; otherwise, outputs remain in a high-impedance state.

Feature Summary

• Provides six non-inverting buffers organized as two four-line and one two-line drivers for bus-oriented applications.
• Features three-state outputs controlled by low-active enable signals to isolate the bus when disabled.
• Designed for high-speed operation with low power consumption and wide operating voltage flexibility.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented receivers

Procurement Notes

Verify the package type matches the required footprint, as the 'E' suffix typically indicates a PDIP-16 package. Confirm the specific revision level against the manufacturer datasheet to ensure compatibility with existing design constraints. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the system requirements.

Selection Notes

Select this component for designs requiring high-speed buffering with tri-state control capabilities. It is suitable for interfacing between different logic families due to its ability to drive multiple LSTTL loads. Consider the ±6 mA output current for driving moderate capacitive loads on buses. Verify that the 2 V to 6 V supply range aligns with the system power rails.

Part Context

This part belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. It is functionally compatible with other hex buffer variants in the family but offers specific three-state control features. The device is designed to improve performance and density in memory and clock distribution circuits compared to standard non-tri-state buffers.

Replacement Considerations

Check for direct equivalents such as SN74HC367 or CD74HC367M depending on package preference. Verify pinout compatibility before substitution. Ensure the replacement maintains the same voltage and current specifications for reliable operation.
