M74HC367TTR

Overview

The M74HC367TTR is a high-speed CMOS hex bus buffer with non-inverting, three-state outputs manufactured using silicon gate C2MOS technology. It operates within a supply voltage range of 2V to 6V and features balanced propagation delays with a typical tPD of 9ns at VCC = 6V. The device contains six buffers divided into two groups controlled by separate enable inputs (G1 and G2). Outputs are enabled when the respective enable input is low and disabled in a high-impedance state when held high. It offers symmetrical output impedance with |IOH| = IOL = 6mA minimum and includes protection circuits against static discharge.

Feature Summary

• Hex bus buffer architecture with non-inverting logic and three-state outputs
• Dual independent group control via dedicated enable inputs for selective activation
• High noise immunity with defined thresholds relative to supply voltage
• Integrated protection circuits against static discharge and transient excess voltage

Applications

• Bus-oriented memory and signal driving applications
• Clock distribution and buffering
• Voltage translation between different logic families
• Driving capacitive loads in digital systems

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing design integration.

Selection Notes

Select this component for designs requiring high-speed buffering with flexible enable control. Ensure operating voltage stays within the 2V to 6V range. Consider thermal dissipation limits if multiple channels are active simultaneously. Verify compatibility with system noise immunity requirements given the CMOS input structure.
