Specialty Logic Procurement Notes

Verify the specific ordering suffix GKFREP corresponds to the Microstar BGA package and tape-and-reel quantity of 1000 units. Confirm the part number matches the SN74SSTV32852-EP family designation for correct electrical characteristics and pinout compatibility during procurement.

Specialty Logic Selection Notes

Select this component when designing systems requiring widebus registered buffering with SSTL_2 interface compatibility. Ensure the design accommodates the 2.3-V to 2.7-V supply voltage range and utilizes differential clocking. Verify that the -40 °C to 85 °C operating temperature range meets the environmental requirements of the target application.

Specialty Logic Part Context

This part belongs to the Texas Instruments Widebus family, specifically designed as a registered buffer. It is part of the SN74SSTV32852-EP series, which emphasizes controlled baseline manufacturing and enhanced diminishing manufacturing sources support. The device integrates 24 bits of data path functionality into a single package for high-density memory designs.

Specialty Logic Replacement Considerations

Direct replacements include other variants within the SN74SSTV32852-EP family such as the SN74SSTV32852DW or SN74SSTV32852DWR, provided they match the required package type and temperature grade. Verify pinout and electrical specifications before substitution.

Specialty Logic FAQ

What is the function of the RESET input?

The RESET input disables the differential input receivers, resets all registers, and forces all outputs low. It must be held at a valid logic high or low level.

How are data inputs registered?

Data are registered at the crossing of the differential clock signals, specifically when CLK goes high and CLK goes low.

What are the input voltage requirements for the RESET pin?

The RESET input supports LVCMOS switching levels, requiring a high-level input voltage of at least 1.7 V and a low-level input voltage of no more than 0.7 V.
