SN74LV244ATDGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ATDGVR is an octal buffer and line driver manufactured by Texas Instruments. It features 3-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device is organized as two independent 4-bit buffers, each with a separate output-enable (OE) input. It supports mixed-mode voltage operation on all ports and includes Ioff circuitry for partial-power-down mode. Typical propagation delay is 5.4 ns at 5 V. Latch-up performance exceeds 250 mA per JESD 17 standard.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP package and tape-and-reel quantity when sourcing. Confirm that the design environment strictly adheres to the 4.5 V to 5.5 V supply voltage limits. Ensure OE pins are properly pulled up to maintain high-impedance states during power transitions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 5 V logic buffering with 3-state control. The TVSOP package offers a compact footprint suitable for space-constrained layouts. Verify compatibility with existing bus architectures and ensure the application does not require voltages outside the specified 4.5 V to 5.5 V operating range.

Buffers, Drivers, Receivers, Transceivers FAQ

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

The device incorporates Ioff circuitry that automatically disables the outputs, preventing damaging current backflow through the device when it is powered down.

What is the function of the OE pin?

When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs enter a high-impedance state.
