SN74LVT162245AZRDR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT162245AZRDR is a 3.3-V ABT 16-bit bus transceiver with 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and supports an operating temperature from -40 °C to +85 °C. The device features two independent octal buses (A and B) controlled by direction (DIR) and output-enable (OE) inputs. A-port outputs include equivalent 22-Ω series resistors for signal integrity. Propagation delays are typically 3.7 ns at 3.3 V. The package is FBGA-ZRD.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation allowing 5-V input and output voltages with 3.3-V VCC
• Provides Ioff and power-up 3-state functionality to support hot insertion applications
• Features distributed VCC and GND pins to minimize high-speed switching noise
• Includes equivalent 22-Ω series resistors on A-port outputs to reduce overshoot and undershoot

Buffers, Drivers, Receivers, Transceivers Applications

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

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'ZRDR' corresponds to the FBGA-ZRD package and reel quantity of 1000 units as listed in the official TI ordering information. Confirm that the component meets the required RoHS compliance and lead finish specifications for your assembly process. Ensure the operating temperature range aligns with your system's thermal design constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer with integrated series resistance on one port. It is suitable for applications needing mixed-voltage interface capabilities without external level shifters. Consider the FBGA package size and pinout compatibility during PCB layout planning.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family of logic ICs. It is part of the SN74LVT162245A series, which includes various package options such as TSSOP, SSOP, and other FBGA variants. The ZRDR suffix specifically denotes the lead-free FBGA package configuration available for mass production.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include SN74LVT162245AGRDR (GRD package) or SN74LVT162245ADGGR (TSSOP package). Verify pin-to-pin compatibility and ensure the alternative package meets the same electrical and thermal requirements.
