74VCX162839 - Low Voltage 20-Bit Selectable Register/Buffer

General Description

The VCX162839 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.

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.
