SN74ALVTH16827VR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH16827VR is a 20-bit buffer and line driver manufactured by Texas Instruments, utilizing Advanced BiCMOS technology. It operates at 2.5-V or 3.3-V VCC with support for mixed-mode signal environments, allowing 5-V input and output voltages within a 2.3-V to 3.6-V supply range. The device features two independent 10-bit sections with separate output-enable signals and provides 3-state outputs. It includes active bus-hold circuitry on data inputs to prevent floating buses without external resistors. The component is housed in a 56-pin Thin Very Small-Outline (DGV) package.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused data inputs?

The device incorporates active bus-hold circuitry on all data inputs. This feature holds unused or floating inputs at a valid logic level, eliminating the need for external pullup or pulldown resistors.

What is the behavior of the outputs during power transitions?

The outputs enter a high-impedance state when VCC is between 0 and 1.2 V. This Auto3-State feature prevents driver conflicts during power-up and power-down sequences.
