SN74LVC162244AGQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC162244AGQLR is a 16-bit buffer and driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features inputs tolerant to 5.5 V, facilitating mixed-mode signal operation in systems utilizing both 3.3-V and 5-V logic levels. The device includes equivalent 26-Ω series resistors on output ports to minimize overshoot and undershoot without requiring external components. It supports partial power-down modes via Ioff circuitry for back-drive protection and live insertion applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation GQL corresponds to the required Microstar Junior BGA form factor for your PCB layout. Confirm that the operating temperature range aligns with your system's thermal environment, as this variant is rated for -40°C to 85°C. Ensure ESD handling protocols are strictly followed due to the MOS gate sensitivity described in the documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing high-density bus-oriented receivers or transmitters requiring 16-bit width. It is suitable for memory address drivers and clock distribution where symmetrical active-low output enables are necessary. Consider the 5.5 V input tolerance if interfacing directly with legacy 5-V logic sources without additional level shifting circuits.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC162244A family, which is part of Texas Instruments' Widebus™ family of logic devices. The 'GQL' suffix specifically identifies the 56-ball Microstar Junior BGA package configuration. This family is engineered to improve performance and density in digital logic applications compared to standard counterparts.
