74VCX16838 - Low Voltage 16-Bit Selectable Register/Buffer

General Description

The VCX16838 contains sixteen 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 (CP) signals.

The device operates in a 16-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 (CP) signals. The device operates in a 16-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. The 74VCX16838 is designed for low voltage (1.65V to 3.
