74VHC244BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74VHC244BQ,115 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 5.5 V. The device contains two independent four-bit buffers controlled by separate output enable inputs (nOE). When nOE is HIGH, the outputs enter a high-impedance OFF-state. The component utilizes DHVQFN20 packaging with dimensions of 2.5 mm by 4.5 mm.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Balanced propagation delays for consistent signal timing
• Schmitt-trigger action on all inputs to improve noise immunity
• Inputs accept voltages exceeding the supply voltage (VCC)
• ESD protection compliant with ANSI/ESDA/JEDEC standards

Buffers, Drivers, Receivers, Transceivers Applications

• Memory module address and data bus buffering
• Clock distribution networks requiring high-speed driving
• Bus-oriented transmissions in mixed-voltage systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'BQ' corresponds to the DHVQFN20 package variant during sourcing. Confirm that the ordering information matches the required temperature range specifications. Ensure compatibility with standard surface-mount assembly processes for the selected package type before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring eight buffered channels with tri-state control capabilities. It is suitable for applications demanding CMOS input levels and wide operating voltage ranges. Consider the thermal performance characteristics inherent to the DHVQFN20 package for heat dissipation requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74VHC series of high-speed silicon-gate CMOS logic devices. It serves as a non-inverting buffer or line driver. The BQ suffix specifically designates the DHVQFN20 plastic dual in-line compatible thermal enhanced very thin quad flat package without leads.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other 74VHC244 variants from Nexperia such as the SO20 or TSSOP20 packages. Cross-manufacturer equivalents must be verified against pinout configurations and electrical specifications to ensure functional compatibility.
