Frequently Asked Questions
What is the SN74ABT861DW and what does it do?
The SN74ABT861DW is a 20-bit bidirectional bus transceiver with 3-state outputs from Texas Instruments. It belongs to the ABT (Advanced BiCMOS Technology) logic family and supports independent output enable control for each direction, making it suitable for high-speed data bus interfacing in microprocessor and memory systems.
What are the key electrical specifications of the SN74ABT861DW?
The SN74ABT861DW operates with a load capacitance (CL) of 50 pF and is designed for standard 5V ABT logic levels. It features 20 bidirectional I/O bits, 3-state outputs, and an independent control pin for each transfer direction. The device is housed in a 24-pin SOIC package (JESD-30 code R-PDSO-G24) and is RoHS-compliant with JESD-609 e4 lead-free rating.
What are the typical applications for the SN74ABT861DW?
Typical applications include CPU-to-memory bus buffering, backplane data transceivers, multi-master bus systems, and FPGA/DSP board I/O expansion. The bidirectional 20-bit width and independent direction control make it especially useful in industrial controllers, networking equipment, and embedded systems requiring parallel data path management.
What package does the SN74ABT861DW come in, and are there compatible alternatives?
The SN74ABT861DW comes in a 24-pin wide SOIC package (DW suffix). Compatible alternatives within the same family include the SN74ABT861DBR (SSOP package) and SN74ABT861PW (TSSOP-24). For drop-in functional equivalents, look for other ABT or LVTH-family 20-bit bus transceivers with the same pinout and 3-state control.
