SN74ABT16245ADL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT16245ADL is a 16-bit noninverting bus transceiver with 3-state outputs from the Texas Instruments Widebus family. It operates on a 4.5-V to 5.5-V supply and features high-drive outputs of -32 mA (IOH) and 64 mA (IOL). The device utilizes an EPIC-IIB BiCMOS design for reduced power dissipation and includes distributed VCC/GND pins to minimize switching noise. It supports synchronous two-way communication between data buses, configurable as one 16-bit or two 8-bit transceivers.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP-48 package and tube packaging format. Confirm that the component meets RoHS compliance standards and matches the required operating temperature range of -40°C to +85°C for industrial applications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed bidirectional data transfer is required at 5-V logic levels. The ABTH series offers faster propagation delays compared to standard LVC or LVTH families. Ensure the application can accommodate the higher drive current capabilities and the specific 4.5-V to 5.5-V supply voltage requirements.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle power-up and power-down states?

The device maintains a high-impedance state during power-up and power-down when VCC is between 0 and 2.1 V, preventing unintended bus driving.

What is the latch-up performance rating?

Latch-up performance exceeds 500 mA per JESD 70, ensuring robust protection against destructive latch-up events under normal operating conditions.
