HEF40098BT,653

Overview

The HEF40098BT,653 is a hex inverting buffer with 3-state outputs manufactured by Nexperia. It operates within a recommended VDD power supply range of 3 V to 15 V referenced to VSS. The device features two active LOW enable inputs (1OE and 2OE) that control the high-impedance state. Four buffer elements are controlled by 1OE, while the remaining two are controlled by 2OE. It complies with JEDEC standard JESD 13-B and supports fully static operation.

Feature Summary

• Hex inverting buffer with 3-state outputs
• Dual active LOW enable inputs for output control
• Fully static operation capability
• Compliance with JEDEC standard JESD 13-B

Applications

• Industrial applications

Procurement Notes

Verify the specific ordering suffix '653' against the manufacturer's current documentation to ensure correct packaging and reel specifications. Confirm that the SO16 plastic small outline package matches the design requirements. Ensure compatibility with the specified operating temperature range of -40 °C to +85 °C for the intended environment.

Selection Notes

Select this component when a hex inverting buffer with tri-state functionality is required. The dual enable inputs allow flexible grouping of outputs into high-impedance states. Verify that the input voltage levels and propagation delays meet the system timing constraints at the operating supply voltage.

Part Context

This part belongs to the HEF4000B series of CMOS logic devices from Nexperia. It provides buffering and inversion functions suitable for general-purpose digital logic applications. The device is designed for robust performance across a wide supply voltage range and industrial temperature conditions.

Replacement Considerations

Check for direct pin-compatible alternatives within the HEF4000B family or other manufacturers offering hex inverting buffers with 3-state outputs. Ensure equivalent electrical characteristics, particularly regarding output drive strength and propagation delay, are maintained.
