SN74HCS244DGSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCS244DGSR is an octal buffer and line driver featuring Schmitt-trigger inputs and three-state outputs. It operates within a wide supply voltage range of 2 V to 6 V, supporting extended ambient temperatures from -40°C to +125°C. The device provides low power consumption with typical ICC of 100 nA and input leakage current of ±100 nA. It offers output drive capabilities up to ±7.8 mA at 6 V. Packaged in a DGS (SOT) 20-pin surface-mount format, it includes two banks of four drivers controlled by separate output enable pins.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix DGSR corresponds to the SOT-20 form factor required for your PCB layout. Confirm that the manufacturing revision matches your production timeline, as datasheet updates may occur. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity. Cross-reference the RoHS status with environmental compliance requirements for your target market before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger architecture. It is suitable for applications requiring signal buffering across wide voltage ranges up to 6 V. Consider the extended temperature rating for harsh environments. Verify that the three-state functionality aligns with your bus management needs. Ensure the SOT-20 package fits within your available board space constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HCS244 family of octal buffers. It shares functional similarities with other 74-series logic devices but distinguishes itself through Schmitt-trigger inputs and wider voltage tolerance. It serves as a robust interface solution between microcontrollers and peripheral devices requiring signal conditioning and isolation.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other SN74HCS244 variants with different packaging options such as RKS (VQFN). Check for equivalent parts from other manufacturers offering HCS logic families with similar pinouts and electrical characteristics. Ensure any replacement maintains the Schmitt-trigger input requirement if noise immunity is essential.
