6V Tolerant Inputs and Outputs 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.
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.
6V) VCC applications with I/O compatibility up to 3.
6V.
The 74VCX16838 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.

0V VCC ±18 mA @ 2.
3V VCC ±6 mA @ 1.
65V VCC s Uses patented noise/EMI reduction circuitry s Ideal for SDRAM DIMM modules s Latch-up performance exceeds 300 mA s ESD performance: Human body model > 2000V Machine model > 200V Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
