MC74HCT365ADG

Overview

The MC74HCT365ADG is a hex bus buffer manufactured by onsemi, belonging to the HCT 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 4.5 V to 5.5 V and supports output currents of 6 mA for both high and low states. It functions reliably across an extended temperature range from -55 °C to +125 °C and is housed in a 16-pin SOIC package.

Feature Summary

• Hex configuration providing six independent non-inverting buffer channels
• Three-state output capability allowing high-impedance disengagement
• Dual enable input control mechanism for synchronized activation
• CMOS construction ensuring low static power consumption

Applications

• Bus-oriented memory and address driver circuits
• Clock drivers and buffering applications
• High noise immunity signal transmission lines

Procurement Notes

Verify the specific suffix 'DG' corresponds to the SOIC-16 tube packaging format as indicated in distributor records. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design to avoid compatibility issues.

Selection Notes

Select this component when interfacing CMOS logic with TTL-compatible loads requiring higher drive current than standard HC series devices provide. The HCT series ensures voltage level compatibility with 5 V TTL systems while maintaining CMOS noise immunity. Consider the dual enable structure for complex bus arbitration requirements where multiple data sources must share a common line without contention.

Part Context

This part belongs to the MC74HCT365A family of hex bus buffers. It serves as a digital logic interface component designed for high-speed data transfer applications. The device is part of onsemi's broader portfolio of compatible logic ICs, offering pin-for-pin replacement options within the same functional family for design flexibility and supply chain resilience.

Replacement Considerations

MC74HCT365ADR2G is a parameter-equivalent alternative available in tape-and-reel packaging.
