General Description
The ALVC16839 contains twenty non-inverting selectable buffered or registered paths. The device can be configured to operate in a registered, or flow through buffer mode by utilizing the register enable (REGE) and Clock (CLK) signals. The device operates in a 20-bit word wide mode. All outputs can be placed into 3-STATE through use of the OE pin. These devices are ideally suited for buffered or registered 168 pin and 200 pin SDRAM DIMM memory modules.
