Description

The HD74ALVCH16244 is designed specifically to improve both the performance and density of three 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 true outputs and symmetrical OE (active-low output-enable) inputs. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

Features

? VCC = 2.3 V to 3.6 V

? Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)

? Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)

? Bus hold on data inputs eliminates the need for external pullup / pulldown resistors
