SN74LV244ADGSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ADGSR is an octal buffer and line driver manufactured by Texas Instruments, utilizing CMOS technology. It operates within a supply voltage range of 2 V to 5.5 V and features balanced three-state outputs. The device is organized into two independent four-bit drivers, each with its own output-enable input. It supports mixed-mode voltage operation on all ports and includes Ioff circuitry for partial-power-down mode. The component is housed in a DGS (VSSOP) package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'DGSR' corresponds to the VSSOP-20 package and tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the specific revision level matches design requirements. Validate that the thermal resistance values align with the intended PCB layout and ambient operating conditions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight buffered channels with independent control over two groups of four. It is suitable for applications needing mixed-voltage interface capabilities between different logic families. Ensure the load capacitance remains within recommended limits to maintain signal integrity and switching performance specifications.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

The Ioff circuitry disables all outputs when the supply pin is held at 0 V, preventing current sourcing or sinking regardless of input voltages.

What is the maximum propagation delay?

The maximum propagation delay is 6.5 ns when operating at a 5 V supply voltage.
