SN74LVT162245AGQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT162245AGQLR is a 3.3-V ABT 16-bit bus transceiver with 3-state outputs, part of the Texas Instruments Widebus family. It operates within a supply voltage range of 2.7 V to 3.6 V and supports mixed-mode signal operation, allowing 5-V input and output voltages with a 3.3-V VCC. The device features distributed VCC and GND pins to minimize high-speed switching noise and includes Ioff and power-up 3-state support for hot insertion applications. It provides TTL interface capability to 5-V system environments.

• Includes Ioff and power-up 3-state circuitry to prevent damaging current backflow during hot insertion
• Features distributed VCC and GND pins to minimize high-speed switching noise
• A-port outputs contain equivalent 22-ohm series resistors to reduce overshoot and undershoot

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between two data buses
• Hot-insertion applications requiring controlled power-up and shutdown states
• Mixed-mode signal interfaces connecting 5-V systems with 3.3-V components

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package marking LZ245A corresponds to the GQL VFBGA variant. Confirm that the ordering suffix 'GQLR' indicates the correct temperature range and reel packaging. Ensure compatibility with the 56-ball FBGA footprint requirements for the target PCB design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer with 3.3-V logic levels. It is suitable for applications needing 5-V tolerance on I/O lines without external level shifters. Consider the VFBGA package constraints if space-saving surface-mount assembly is required.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle hot insertion?

The device supports hot insertion through Ioff and power-up 3-state circuitry, which disables outputs and prevents damaging current backflow when powered down or during power-up.

What is the function of the A-port series resistors?

The A-port outputs include equivalent 22-ohm series resistors designed to reduce overshoot and undershoot, eliminating the need for external resistors.
