CLVTH32244IGKEREP-Enhanced Product 3.3-V Abt 32-Bit Buffer/Driver With 3-State Outputs

The SN74LVTH32244 is a 32-bit buffer and line driver designed for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment. This device can be used as eight 4-bit buffers, four 8-bit buffers, two 16-bit buffers, or one 32-bit buffer. The device provides true outputs and has symmetrical active-low output-enable (OE)\ inputs. It is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

When VCC is between 0 and 1.5-V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5-V, OE\ shall be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.
