SN74HC244QDWREP

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC244QDWREP is a military-enhanced octal buffer and line driver manufactured by Texas Instruments. It belongs to the HC logic series and features eight non-inverting channels with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V, drawing a maximum static current of 8 uA and an operating supply current of 80 uA. It supports high-level output currents of -7.8 mA and low-level output currents of 7.8 mA. The component functions reliably across an extended temperature range from -55 C to +125 C, with a propagation delay of 165 ns at 2 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific Q suffix indicates military enhancement standards when sourcing. Confirm the DWEP or similar suffix aligns with the required tape-and-reel packaging format. Ensure the order matches the exact SN74HC244QDWREP designation to guarantee compliance with specified temperature ranges and electrical characteristics defined by the manufacturer.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring wide voltage operation down to 2 V combined with extended temperature capabilities. The HC series offers CMOS compatibility while maintaining standard logic levels. Consider the SOIC-20 package dimensions for PCB layout constraints. Verify that the three-state functionality meets system bus isolation requirements without additional gating logic.
