74LVC16245ABQ,518

Overview

The 74LVC16245ABQ,518 is a 16-bit bus transceiver manufactured by NXP Semiconductors. It features non-inverting 3-state outputs and operates within a supply voltage range of 1.2 V to 3.6 V. The device supports 5 V tolerant inputs and outputs, allowing direct interfacing with 5 V logic devices. It includes two output enable (nOE) inputs and two send/receive (nDIR) direction control inputs. The component utilizes an HXQFN60U package (SOT1134-1) with a body size of 4 x 6 x 0.5 mm. It is specified for operation from -40 °C to +125 °C.

Feature Summary

• Provides bidirectional data transmission between buses using dual direction control inputs.
• Features 5 V tolerant I/Os for safe interfacing with mixed 3.3 V and 5 V logic systems.
• Includes high-impedance state when VCC is 0 V to prevent back-powering during power-down.

Applications

• Mixed voltage system interconnects
• Memory bus expansion
• High-density data routing

Selection Notes

Select this component for designs requiring 16-bit bidirectional data transfer in space-constrained applications. The HXQFN60U package offers a compact footprint suitable for high-density PCB layouts. Ensure the design accommodates the required thermal dissipation characteristics associated with this package type under maximum operating conditions.

Part Context

This part belongs to the 74LVC16245A family of 16-bit bus transceivers. It shares functional specifications with variants such as the 74LVC16245ADL and 74LVC16245AEV, differing primarily in the physical package configuration. The ABQ variant specifically denotes the extremely thin quad flat package without leads.

Replacement Considerations

Direct replacements include other packages within the same family, such as 74LVC16245ADL or 74LVC16245AEV, provided the board layout can accommodate the respective package dimensions.
