Key Features
- 16-bit bidirectional bus transceiver with 3-state outputs enables high-bandwidth data transfer between two buses with active direction control
- Common output enable and direction control simplifies bus arbitration logic with a single enable pin for all 16 channels simultaneously
- 64mA output sink current capability drives heavy bus loads including backplane traces and multiple receivers with low voltage drop
- ABT logic family provides fast switching speeds and reduced output undershoot voltage (typ VOLP < 1V at 5V VCC) for clean bus transitions
Applications
The SN74ABT16245DGGR is widely used in data bus buffering and level translation between processors, FPGAs, ASICs, and memory systems in high-speed digital designs. Its 16-bit width and bidirectional capability make it ideal for address/data bus expansion in embedded computing boards, workstations, and industrial control systems. The 3-state outputs support bus sharing configurations where multiple transceivers connect to a common backplane or memory bus.

Frequently Asked Questions
What is the bit width and direction of the SN74ABT16245DGGR?
The SN74ABT16245DGGR is a 16-bit bidirectional bus transceiver, meaning it can pass data in either direction between two bus ports. Direction is controlled by a dedicated DIR pin, and a common output enable pin (OE) tri-states all outputs simultaneously for bus sharing.
What output current can the SN74ABT16245DGGR sink?
The SN74ABT16245DGGR can sink up to 64mA (Max I(ol) = 0.064A) per output pin. This high sink current is suitable for driving long backplane traces, high-capacitance bus loads of up to 50pF, and multiple parallel receiver inputs in large digital systems.
What is the operating temperature range of the SN74ABT16245DGGR?
The SN74ABT16245DGGR operates over an industrial temperature range of -40°C to +85°C. This range is appropriate for use in industrial control panels, telecommunications equipment, and embedded computing systems that experience wide ambient temperature variation.
What package does the SN74ABT16245DGGR come in?
The SN74ABT16245DGGR is housed in a 48-pin TSSOP (Thin Shrink Small Outline Package, JEDEC R-PDSO-G48) surface-mount package. This thin, fine-pitch package offers a small PCB footprint suitable for high-density board designs with limited space.
Is the SN74ABT16245DGGR RoHS compliant?
The SN74ABT16245DGGR carries a Pb-free code of No, indicating it is not a lead-free part in this specific variant. Designers requiring RoHS compliance should verify the specific suffix and check the Texas Instruments product page for available lead-free alternative part numbers.
