74ABT16245ADGGRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT16245ADGGRG4 is a 16-bit noninverting bus transceiver with 3-state outputs, part of the Texas Instruments Widebus family. It utilizes state-of-the-art EPIC-IIB BiCMOS design for significantly reduced power dissipation and typical output ground bounce below 1 V at VCC = 5 V. Designed for synchronous two-way communication between data buses, it operates within a supply voltage range of 4.5 V to 5.5 V. The device features high-drive outputs capable of -32 mA IOH and 64 mA IOL, ensuring robust signal transmission. It includes distributed VCC and GND pin configurations to minimize high-speed switching noise.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'RG4' corresponds to the TSSOP (DGG) package with lead finish NIPDAU and RoHS compliance as listed in the packaging addendum. Confirm that the moisture sensitivity level is rated Level-1-260C-UNLIM for standard reflow soldering processes. Ensure the operating temperature range of -40°C to 85°C aligns with your system environmental requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit widebus transceiver with high drive strength and low power consumption is required. The EPIC-IIB technology offers advantages over standard CMOS in terms of speed and noise immunity. Consider the TSSOP-48 package dimensions if board space is constrained. Verify that the 4.5 V to 5.5 V supply voltage range matches the target system logic levels.
