SN74ALVCH162827DGGR

The SN74ALVCH162827DGGR from Texas Instruments is a 20-bit noninverting buffer/driver that operates within a VCC range of 1.65V to 3.6V. This device is part of the Widebus family and is structured into two independent 10-bit buffer sections, each controlled by its own output-enable signals.

For the outputs to be active, both output-enable inputs for a given 10-bit section must be low. If either output-enable input is high, the outputs for that section enter a high-impedance state. The outputs are designed to sink up to 12 mA and include integrated 26-ohm series resistors to minimize overshoot and undershoot, eliminating the need for external resistors.

This buffer/driver incorporates bus-hold circuitry on data inputs, which holds unused or undriven inputs at a valid logic state, thus removing the requirement for external pullup or pulldown resistors. Latch-up performance exceeds 250 mA per JESD 17, and ESD protection surpasses JESD 22 standards, including 2000V for the Human-Body Model, 200V for the Machine Model, and 1000V for the Charged-Device Model.

The SN74ALVCH162827DGGR is available in a DGG (TSSOP) package and operates over a temperature range of -40°C to 85°C. It is suitable for applications requiring high-speed data transmission and bus interfacing where precise signal integrity and robust protection are essential.
