Frequently Asked Questions
What makes the SN74ABT8952DW different from a standard bus transceiver?
The SN74ABT8952DW adds registered (clocked) data latching and JTAG boundary scan capability to standard octal bus transceiver function, enabling synchronous data transfer and in-system testability that unregistered transceivers lack.
What is the package type for the SN74ABT8952DW?
The SN74ABT8952DW comes in a 28-pin SOIC package (JESD-30 code R-PDSO-G28), a wide-body surface-mount package suitable for automated PCB assembly in industrial and computing applications.
Does the SN74ABT8952DW support independent output enables?
Yes, the SN74ABT8952DW provides independent output-enable controls for each direction of data transfer, allowing the A-to-B and B-to-A paths to be enabled or disabled independently for flexible bus management.
Is the SN74ABT8952DW RoHS compliant?
Yes, the SN74ABT8952DW carries a Pb-free code of 'Yes' and JESD-609 code e4, confirming compliance with RoHS lead-free requirements for use in environmentally regulated markets worldwide.
What bus speed performance does the ABT family offer?
Texas Instruments' ABT (Advanced BiCMOS Technology) family provides propagation delays typically below 3ns and output drive currents up to 64mA, making the SN74ABT8952DW well-suited for high-speed backplane and processor bus applications operating above 100MHz.
