SN74HC244AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC244AN is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HC logic series. It features eight non-inverting inputs and outputs housed in a SOIC-20 package. The device operates within a supply voltage range of 2 V to 6 V, with a maximum static current of 8 uA and a typical operating supply current of 80 uA. Output drive capabilities include -7.8 mA at high level and 7.8 mA at low level. Propagation delays vary from 130 ns at 2 V to 22 ns at 6 V. It supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AN' against the manufacturer's official documentation to confirm the exact package type and tape/reel specifications. Ensure the ordering part number matches the required lead time and packaging format. Cross-reference the datasheet revision date to confirm compliance with current RoHS standards and material declarations before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when eight-channel buffering with three-state capability is required within standard CMOS voltage ranges. Consider the propagation delay characteristics relative to the system clock speed. Verify that the SOIC-20 package dimensions fit the available PCB footprint and that the thermal performance meets the operational environment requirements without additional heatsinking.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74HC244 family of octal buffers and line drivers. It shares functional similarities with other variants such as SN74HC244APWR and SN74HC244DBR, differing primarily in package style and manufacturing lot specifications. The HC series provides compatibility with standard TTL logic levels while offering improved noise immunity and lower power consumption compared to older logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74HC244DR and SN74HC244DWR for similar SOIC-20 configurations. Verify pinout compatibility and electrical parameters before replacing. Alternative packages like SSOP-20 or TSSOP-20 require mechanical adaptation.
