3.3-V ABT 16-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

The LVTH16244A are 16-bit Buffers and Line Drivers SN54LVTH16244A SN74LVTH16244A designed for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL Interface to a 5-V system environment. These devices CAN be used as four 4-bit Buffers two 8-bit Buffers or one 16-bit Buffer These devices provide true outputs and symmetrical active-low output-enable (OE) inputs. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid Logic level. When VCC is between 0 and 1.5-V, the devices are in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5-V, 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. The SN74LVTH16244A is available in TIs shrink small-outline (DL) and thin shrink small-outline (DGG) packages, which provide twice the I/O pin count and functionality of standard small-outline packages in the same printed circuit board area.
