Frequently Asked Questions
What is the maximum sink current of the SN74BCT25245DW?
The SN74BCT25245DW supports a maximum sink current (IOL) of 24mA at VOL = 0.5V for Port B, and a source current (IOH) of 3mA at VOH = 2.4V. This high drive capability makes it suitable for driving capacitive bus loads up to 50pF.
How does direction control work on the SN74BCT25245DW?
The SN74BCT25245DW uses a common direction control (DIR) pin to set the data flow direction across all 8 channels simultaneously. When DIR is high, data flows from Port A to Port B; when DIR is low, data flows from Port B to Port A, enabling full bidirectional bus transceiver operation.
What package type does the SN74BCT25245DW use and is it Pb-free?
The SN74BCT25245DW comes in a 24-pin wide SOIC package (JESD-30 code: R-PDSO-G24). It is fully Pb-free and RoHS compliant, with JESD-609 code e4, making it suitable for environmentally compliant manufacturing processes.
What are common applications for the SN74BCT25245DW?
Common applications include microprocessor bus buffering, memory interface expansion, industrial control backplanes, and data isolation between logic domains. Its bidirectional 8-bit architecture and high sink current make it a standard choice for system bus management in embedded designs.
