SN74ABT16245ADLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT16245ADLR is a 16-bit noninverting bus transceiver with 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to +85°C. The device features high-drive outputs capable of -32 mA high-level and 64 mA low-level currents. Propagation delays are typically 4.2 ns at 5 V. It utilizes the EPIC-II BiCMOS process for reduced power dissipation and includes distributed VCC/GND pins to minimize switching noise.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Designed for synchronous two-way communication between data buses using a flow-through architecture that optimizes PCB layout.
• Provides high-impedance state during power-up and power-down when VCC is between 0 and 2.1 V.
• Features latch-up performance exceeding 500 mA per JESD 70 standards.

Buffers, Drivers, Receivers, Transceivers Applications

• Synchronous two-way communication between data buses
• Configuration as one 16-bit transceiver or two 8-bit transceivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package marking 'ABT16245A' on the SSOP-48 component to confirm authenticity. Ensure the supply voltage remains strictly within the 4.5 V to 5.5 V range to prevent damage. Confirm that unused inputs are tied to VCC or GND to maintain proper operation. Check for RoHS compliance status if environmental regulations apply to the assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed bidirectional data transfer with significant drive capability. The ABTH logic family offers faster switching speeds compared to standard LVTTL options. Consider the SSOP-48 package constraints regarding thermal impedance and board space. Verify that the system's input transition rates do not exceed the specified limits to ensure signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family, utilizing state-of-the-art EPIC-II BiCMOS design technology. It is part of the SN74ABT16245A series, which provides enhanced performance over previous generations. The ADLR suffix indicates the Shrink Small-Outline (DL) plastic package configuration with tape-and-reel packaging for automated assembly.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ABT16245ADL is a tube-packaged equivalent in the same SSOP-48 form factor. SN74ABT16245ADGGR offers identical electrical characteristics but utilizes a TSSOP-48 package.
