74HC365D,653

Overview

The Nexperia 74HC365D,653 is a hex buffer and line driver featuring three-state outputs controlled by two active-low output enable inputs (OE1 and OE2). It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes CMOS technology for low power dissipation and includes input clamp diodes to interface with voltages exceeding VCC. It is housed in a 16-lead SO16 plastic small outline package (SOT109-1) with a body width of 3.9 mm.

Feature Summary

• Provides non-inverting buffering for six independent data lines with high noise immunity.
• Features three-state outputs that assume a high impedance OFF-state when enabled inputs are HIGH.
• Includes input clamp diodes allowing safe interfacing to voltages higher than the supply voltage.

Applications

• Memory address and data bus drivers
• Clock distribution buffers
• General-purpose digital signal buffering

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status and REACH registration details directly with the manufacturer or authorized distributor before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring wide supply voltage flexibility between 2.0 V and 6.0 V. Ensure the design accommodates the specified operating temperature range up to +125 °C. Verify that the load capacitance requirements align with the dynamic characteristics provided in the datasheet.

Part Context

This part belongs to the 74HC logic family, characterized by CMOS construction and compatibility with standard TTL input levels at higher supply voltages. It serves as a fundamental building block for digital systems requiring signal isolation and drive capability enhancement across multiple channels simultaneously.

Replacement Considerations

The 74HCT365D,653 offers similar functionality but is restricted to a 4.5 V to 5.5 V supply range. Other packages such as TSSOP16 (74HC365PW) provide alternative form factors with identical electrical performance.
