description

This 20-bit inverting buffer/driver is designed for 2.7-V to 3.6-V V_CC operation.

The SN74ALVC16828 is composed of two 10-bit sections with separate output-enable signals. For either 10-bit buffer section, the two output-enable (1 and 1or 2and 2) inputs must both be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 10-bit buffer section are in the high-impedance state.

The SN74ALVC16828 is available in TI's 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.

The SN74ALVC16828 is characterized for operation from -40°C to 85°C.
