Copyright © 2005, Texas Instruments Incorporated SN74LVC16244A-Q1 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS www.ti.com SCES631 – MAY 2005 DESCRIPTION/ORDERING INFORMATION (CONTINUED) The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and symmetrical active-low output-enable (OE) inputs. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
