SN74SSTU32864ZKER

The SN74SSTU32864ZKER from Texas Instruments is a versatile 25-bit configurable registered buffer, part of the Widebus+ family. It operates with a VCC supply voltage ranging from 1.7V to 1.9V and is designed to optimize DDR-II DIMM PCB layout.

This device can be configured as either a 25-bit 1:1 or a 14-bit 1:2 registered buffer. It features SSTL_18 compatible data inputs and LVCMOS compatible control and reset inputs. The outputs are edge-controlled circuits optimized for unterminated DIMM loads and meet SSTL_18 specifications. Differential clock inputs (CLK and CLK) are supported, with data registered at the crossing of CLK going high and CLK going low.

The SN74SSTU32864ZKER includes chip-select inputs that gate the data outputs from changing state, minimizing system power consumption. The RESET input disables differential input receivers, resets all registers, and forces all outputs low. Latch-up performance exceeds 100 mA per JESD 78, Class II, and ESD protection exceeds JESD 22 standards.

Packaged in a 96-LFBGA, this surface-mount component is suitable for applications requiring high-speed data buffering and registration in memory modules. The operating temperature range is 0°C to 70°C.
