MC74HC365ADR2

Overview

The MC74HC365ADR2 is a hex bus buffer manufactured by onsemi, belonging to the HC logic series. It features six non-inverting buffers with three-state outputs controlled by two enable inputs. The device operates within a supply voltage range of 2 V to 6 V and supports surface mount installation in a TSSOP-16 package. Key electrical parameters include a propagation delay of 20 ns, high-level output current of -7.8 mA, low-level output current of 7.8 mA, and static current of 4 uA. It functions reliably across an operating temperature range from -55 C to +125 C.

Feature Summary

• Hex configuration providing six independent non-inverting buffer channels
• Three-state output capability allowing high-impedance disconnection for bus sharing
• Dual enable input control mechanism for precise signal gating

Applications

• Bus-oriented memory and address driver circuits
• Clock drivers and buffer circuits
• Multiplexer receivers

Procurement Notes

Verify the exact suffix against official documentation, as 'ADR2' may indicate specific packaging or tape-and-reel configurations distinct from standard variants. Confirm RoHS compliance status through manufacturer declarations. Ensure the ordering code matches the required pinout and electrical specifications for the target application design.

Selection Notes

Select this component when designing systems requiring multiple buffered signals with tri-state isolation capabilities. The HC series offers compatibility with standard CMOS logic levels while providing sufficient drive strength for moderate capacitive loads. Consider the wide voltage range and industrial temperature rating for robust performance in diverse environments.

Part Context

This part belongs to the MC74HC365A family of hex bus buffers produced by onsemi. These devices are designed for high-speed digital applications where signal integrity and bus management are critical. The HC technology ensures low power consumption alongside fast switching speeds, making them suitable for complex digital systems.

Replacement Considerations

MC74HC365ADTR2G is a verified substitute offering identical functionality in a TSSOP-16 package with reel packaging.
