description

This 16-bit buffer/driver is designed for 1.65-V to

The SN74ALVCH16240 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 four 4-bit buffers, two

8-bit buffers, or one 16-bit buffer. It provides

inverting outputs and symmetrical active-low

output-enable (OE) inputs.

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 SN74ALVCH16240 is characterized for operation from –40

°C to 85°C.
