SN74ALVTH16244VR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH16244VR is a 16-bit buffer and line driver manufactured by Texas Instruments, utilizing Advanced BiCMOS Technology (ABT) for 3.3-V operation with low static-power dissipation. It features 3-state outputs and supports mixed-mode signal operation, allowing 5-V input and output voltages while operating at 3.3 V. The device accommodates unregulated battery operation down to 2.3 V and includes active bus-hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors. Packaged in a TVSOP-48 format, it provides high drive capability of -32 mA/64 mA.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle floating inputs?

The device incorporates active bus-hold circuitry on its data inputs, which holds unused or floating inputs at a valid logic level without requiring external pullup or pulldown resistors.

What is the purpose of the Auto3-State feature?

The Auto3-State function automatically places the outputs in a high-impedance state when the voltage at the output exceeds VCC, thereby eliminating bus current loading.
