M74HC365TTR

Overview

The M74HC365TTR is a hex bus buffer with three-state outputs manufactured by STMicroelectronics. It operates within a supply voltage range of 2 V to 6 V and features non-inverting logic. The device utilizes advanced high-speed CMOS technology, providing symmetrical output impedance and balanced propagation delays. It includes input protection against static discharge and transient excess voltage. The component is housed in a 16-TSSOP surface-mount package.

Feature Summary

• Hex bus buffer configuration with three-state outputs controlled by two enable inputs
• Advanced high-speed CMOS fabrication ensuring low power dissipation
• High noise immunity with wide operating voltage range from 2 V to 6 V

Applications

• Data acquisition systems requiring signal buffering
• Clock distribution networks for digital circuits
• Memory interface buffers in embedded systems

Procurement Notes

Verify the specific suffix 'TTR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-TSSOP footprint matches the target PCB design constraints. Ensure compliance with RoHS directives if applicable to the manufacturing environment. Cross-reference the manufacturer part number with official distributor catalogs to validate current production status and availability.

Selection Notes

Select this component when a six-channel non-inverting buffer with high-impedance state control is required. The wide voltage range supports various logic families. Consider the TSSOP package for space-constrained designs. Verify that the propagation delay characteristics meet the system timing requirements. Ensure adequate thermal management for the intended operating temperature range.

Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It serves as a direct replacement for legacy 74LS365 parts in many applications due to pin compatibility. The device is designed for general-purpose digital signal buffering and driving tasks in consumer electronics and industrial control systems.
