Frequently Asked Questions
What is the SN74ABTH245DWG4 and what logic family does it belong to?
The SN74ABTH245DWG4 is an 8-bit non-inverting bidirectional bus transceiver from Texas Instruments' ABT (Advanced BiCMOS Technology) logic family. It supports common control with direction control, allowing bidirectional data flow between two 8-bit buses using a single DIR pin.
What is the output sink current capability of the SN74ABTH245DWG4?
The SN74ABTH245DWG4 provides a maximum low-level output sink current (I_OL) of 64 mA (0.064 A), which is significantly higher than standard CMOS logic families. This high drive strength makes it suitable for driving heavily loaded backplane buses, long PCB traces, and multi-drop bus configurations.
What package does the SN74ABTH245DWG4 use?
The SN74ABTH245DWG4 is housed in a 20-pin SOIC package (JESD-30 Code R-PDSO-G20) with a 50 pF load capacitance specification. It is RoHS-compliant per JESD-609 Code e4. The SOIC package supports standard SMT assembly processes and offers a compact footprint for board-level integration.
What are typical applications for the SN74ABTH245DWG4 bus transceiver?
This device is widely used in microprocessor data buses, memory bus buffering, PCI and ISA backplane interfaces, and multi-board computing systems where bidirectional high-drive signal switching is needed. Its 8-bit width, direction control, and ABT-family performance also suit FPGA I/O expansion, VMEbus interfaces, and industrial controller I/O subsystems.
