SN74SSTU32864ZKER

Specialty Logic Overview

The SN74SSTU32864 is a 25-bit configurable registered buffer designed for 1.7-V to 1.9-V VCC operation, featuring SSTL_18 inputs and outputs. It supports differential clock inputs (CLK and CLK) with data registration at the crossing of rising and falling edges. The device operates within a temperature range of 0°C to 70°C and utilizes a 96-pin LFBGA package.

Specialty Logic Feature Summary

• Configurable as a 25-bit 1:1 or 14-bit 1:2 registered buffer
• Output edge-control circuitry minimizes switching noise in unterminated lines
• Chip-select inputs gate data outputs to minimize system power consumption
• RESET input disables differential receivers and forces all outputs low

Specialty Logic Applications

• DDR-II DIMM PCB layout optimization
• Driving SDRAM loads in memory modules
• High-speed digital signal buffering

Specialty Logic Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Confirm that the component meets RoHS compliance standards and check the active production status before procurement planning.

Specialty Logic Selection Notes

Select this component when designing systems requiring SSTL_18 compatibility and configurable bus widths. Ensure the design accommodates the required 1.7-V to 1.9-V supply voltage and differential clocking architecture. Verify pinout configuration requirements for 1:1 versus 1:2 modes during the schematic phase.

Specialty Logic Part Context

This part belongs to the Texas Instruments Widebus+ family of logic ICs. It serves as a registered buffer solution optimized for high-density memory applications, specifically addressing the routing constraints associated with DDR-II standard implementations.

Specialty Logic Replacement Considerations

Consult official substitution guides for equivalent widebus register buffers. Verify pin-to-pin compatibility and electrical parameter alignment with alternative TI series members before implementation.
