SN74LVT244BGQNR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT244BGQNR is an octal buffer and line driver designed for low-voltage 3.3-V VCC operation with TTL interface capability to 5-V systems. It supports unregulated battery operation down to 2.7 V. The device features Ioff and power-up 3-state support for hot insertion, preventing damaging current backflow during power-down or conflicts during power-up. Latch-up performance exceeds 100 mA per JESD 78, Class II, and ESD protection exceeds 2000-V human-body model, 200-V machine model, and 1000-V charged-device model.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific GQN package variant against the official datasheet SCAS354J to confirm pinout and thermal characteristics. Ensure design compatibility with the recommended operating conditions, specifically the 2.7-V to 3.6-V supply voltage range. Confirm that the application environment respects the absolute maximum ratings for input and output voltages to prevent device damage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer is required for 3.3-V logic families interfacing with 5-V legacy systems. The GQN package offers a compact footprint suitable for space-constrained designs. Consider the device's propagation delay and drive strength if high-speed data transmission is critical to the system architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVT244B series of octal buffers and line drivers from Texas Instruments. It is functionally compatible with other variants in the family, such as those in SOIC or TSSOP packages, differing primarily in physical form factor and mounting style. The series is engineered for low-voltage digital applications requiring robust signal integrity and mixed-voltage tolerance.
