description
This 32-bit buffer/driver is designed for 1.65-V to 3.6-V V_CC operation.
The SN74ALVCH32244 is designed specifically to improve the performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented receivers and transmitters.
The device can be used as eight 4-bit buffers, four 8-bit buffers, two 16-bit buffers, or one 32-bit buffer. It provides
true outputs and symmetrical active-low output-enable (OE) inputs.
To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH32244 is characterized for operation from –40°C to 85°C.
