SN74ABT16245ADLRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT16245ADLRG4 is a 16-bit noninverting bus transceiver with 3-state outputs from the Texas Instruments Widebus family. It utilizes state-of-the-art EPIC-IIB BiCMOS design for synchronous two-way communication between data buses, functioning as either one 16-bit or two 8-bit transceivers. The device operates at a supply voltage of 4.5 V to 5.5 V and supports a low-level output current of 64 mA and a high-level output current of -32 mA. Propagation delay ranges from 0.5 ns to 4.6 ns depending on direction and load conditions. It features distributed VCC and GND pin configurations to minimize high-speed switching noise.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the required SSOP-48 form factor. Confirm the operating temperature range aligns with industrial specifications (-40°C to +85°C). Ensure the RoHS compliance status meets environmental requirements. Check that the lead finish corresponds to NIPDAU specifications for solderability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high drive strength and fast propagation delays are required for 16-bit wide data paths. The ABT logic series offers superior speed compared to standard CMOS alternatives. Consider the flow-through pinout if minimizing trace length and crosstalk is critical for signal integrity in dense layouts.
