HEF40098BP,652

Overview

The HEF40098BP,652 is a hex inverting buffer with 3-state outputs manufactured by NXP USA Inc. 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 of the outputs. Unused inputs must be connected to VDD, VSS, or another input. It complies with JEDEC standard JESD 13-B and supports fully static operation.

Feature Summary

• Hex inverting buffer with 3-state outputs controlled by two active LOW enable inputs
• Fully static operation with standardized symmetrical output characteristics
• Complies with JEDEC standard JESD 13-B

Applications

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and compliance status. Confirm the manufacturer designation as Nexperia for this part number. Ensure compatibility with system voltage levels and temperature ranges before procurement.

Selection Notes

Select this component for designs requiring hex inverting buffers with tri-state capability. Verify that the operating voltage falls between 3 V and 15 V. Consider the propagation delay characteristics relative to the load capacitance and supply voltage when designing timing-critical circuits.

Part Context

This component belongs to the HEF40098B series, which are hex inverting buffers with 3-state outputs. The BP variant indicates a specific packaging configuration. The datasheet revision history notes changes in product specifications and legal information over time.

Replacement Considerations

Check for direct substitutes within the HEF40098B family or compatible hex inverting buffers with 3-state outputs from other manufacturers. Ensure pinout compatibility and electrical specifications match the original design requirements.

FAQ

How are the 3-state outputs controlled?

The 3-state outputs are controlled by two active LOW enable inputs (1OE and 2OE). A HIGH on 1OE causes four outputs to assume a high-impedance state, while a HIGH on 2OE affects the remaining two outputs.

What is the recommended power supply range?

The device operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS.
