SN74SSTU32864GKER

Specialty Logic Overview

The SN74SSTU32864GKER is a 25-bit configurable registered buffer from the Texas Instruments Widebus+ family, designed for 1.7-V to 1.9-V VCC operation. It supports SSTL_18 inputs and outputs with differential clock inputs (CLK and CLK). The device registers data at the crossing of the rising edge of CLK and the falling edge of CLK. It features chip-select inputs (DCS and CSR) that gate data outputs to minimize system power consumption. The component operates within an ambient temperature range of 0°C to 70°C.

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 reduce 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
• Registered buffering for high-speed digital interfaces

Specialty Logic Procurement Notes

Verify the specific ordering suffix GKE against the manufacturer's current package options list to confirm the tape and reel configuration. Ensure the voltage supply requirements align with the recommended operating conditions before integration. Confirm the availability status directly with authorized distributors as production data may change.

Specialty Logic Selection Notes

Select this component when designing DDR-II compliant systems requiring optimized pinout layouts. The device supports both LVCMOS control levels and SSTL_18 data signaling. Consider the 1:1 versus 1:2 configuration needs based on the number of SDRAM loads per DIMM. Verify that the differential clock inputs match the system timing requirements.

Specialty Logic Part Context

This part belongs to the Texas Instruments Widebus+ family of logic ICs. It is specifically engineered for memory interface applications where signal integrity and power efficiency are critical. The device integrates edge-controlled output drivers tailored for unterminated DIMM loads, distinguishing it from standard buffered components.
