SN74LVCH16245ADL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH16245ADL is a 16-bit (dual-octal) noninverting bus transceiver with 3-state outputs from the Texas Instruments Widebus family. It operates from 1.65 V to 3.6 V and features inputs accepting voltages up to 5.5 V, supporting mixed-mode signal operation in 5-V input/output environments with 3.3-V VCC. The device provides asynchronous communication between data buses with a maximum propagation delay of 4 ns at 3.3 V. It includes active bus-hold circuitry on data inputs to eliminate external pullup or pulldown resistors. The SSOP-48 package measures 15.88 mm by 7.49 mm.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused data inputs?

The SN74LVCH16245ADL utilizes active bus-hold circuitry on its data inputs. This feature holds unused or undriven inputs at a valid logic state, eliminating the requirement for external pullup or pulldown resistors.

What is the function of the Ioff circuitry?

The Ioff circuitry disables the outputs when the device is powered down. This prevents damaging current backflow through the device, thereby supporting live insertion and partial-power-down modes.
