SN74LV244ATNS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244AT is an octal buffer and line driver featuring three-state outputs, designed for high-performance memory address drivers, clock drivers, and bus-oriented receivers. It operates within a supply voltage range of 4.5 V to 5.5 V. The device consists of two independent 4-bit buffers with separate output-enable inputs. Key electrical characteristics include a typical propagation delay of 5.4 ns at 5 V, TTL-voltage compatible inputs, and latch-up performance exceeding 250 mA per JESD 17 standards.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (e.g., DW, PW, NS) against the required PCB footprint. Confirm RoHS compliance status as indicated in the ordering information. Ensure the operating temperature range (-40°C to 85°C) matches the system environment requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a wide supply voltage range of 4.5 V to 5.5 V is required. It is suitable for applications needing TTL-compatible input levels and high-density bus driving. Consider the Ioff feature if partial power-down capabilities are necessary for the design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV244A family of octal buffers/drivers. It shares functional similarities with other members but is specifically characterized for the 4.5 V to 5.5 V operating range. The 'AT' suffix typically denotes specific testing or manufacturing lot attributes defined by Texas Instruments.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial-power-down scenarios?

The device supports partial-power-down mode through its Ioff circuitry, which automatically disables the outputs to prevent damaging current backflow when the device is powered down.

What is the input compatibility of the SN74LV244AT?

The inputs are TTL-voltage compatible, allowing them to interface directly with TTL logic sources while operating within the specified 4.5 V to 5.5 V supply range.
