SN74LVC244APWR Texas Instruments Octal Buffer/Driver, TSSOP-20 - Full Reel of 2,000
Overview
SN74LVC244APWR from Texas Instruments is an octal buffer and line driver with 3-state outputs. It belongs to the SN74LVC244A logic family and is supplied in a compact TSSOP-20 surface-mount package for production assembly.
This device is used when a digital design needs buffered signal drive, bus isolation, or controlled high-impedance outputs between logic domains. The LVC family supports low-voltage operation from 1.65 V to 3.6 V, while the inputs can tolerate up to 5.5 V, making the part useful in mixed-voltage logic systems when the datasheet conditions are followed.

Design and Selection Notes
The SN74LVC244APWR should be selected when the target board needs an eight-channel non-inverting buffer with 3-state output control. Check the output-enable polarity, pinout, supply rail, input signal levels, drive current, bus loading, and timing margin before design release.
Because the device has 3-state outputs, it can share a bus only when output-enable timing prevents contention. Designers should also confirm whether the system needs input overvoltage tolerance, partial-power-down behavior, and IOFF support. These details are controlled by the Texas Instruments datasheet and should be reviewed against the final schematic and operating conditions.
For substitutions, compare the full ordering code, package, pinout, temperature grade, logic family, output drive, propagation delay, and tape-and-reel requirements. Similar 74LVC244 devices from different manufacturers may not be identical in timing, package options, ordering codes, or qualification status.
Applications
- Buffered address, data, and control lines in embedded systems.
- Low-voltage digital logic distribution on 1.8 V, 2.5 V, and 3.3 V rails.
- Bus isolation and output-enable controlled logic paths.
- Microcontroller, FPGA, CPLD, and processor support circuitry.
- Mixed-voltage interface designs where 5.5 V tolerant inputs are useful and datasheet limits are met.
- Industrial control, communications, computing, and general digital electronics assemblies.
- Production builds requiring full-reel TSSOP-20 material for automated SMT placement.

FAQ
What is SN74LVC244APWR best suited for?
SN74LVC244APWR is best suited for buffering, driving, and isolating eight digital signals on low-voltage logic boards that need non-inverting 3-state outputs.
What supply voltage range does the LVC244A family support?
Texas Instruments lists operation from 1.65 V to 3.6 V. Check propagation delay, output drive, and input thresholds at the exact VCC used in the design.
Can the inputs accept 5 V signals?
TI states that inputs accept voltages to 5.5 V, allowing selected mixed-voltage use cases. The output high level still follows the device VCC, so verify the receiving logic thresholds.
What does the 3-state output feature do?
3-state outputs let the buffer disconnect from a bus when output enable is inactive. Designers must sequence output-enable signals to avoid bus contention.
Can this device be used as a level translator?
It can be used for down-translation from higher input levels to the VCC output level under datasheet conditions. It is not a general bidirectional level shifter.
What does order quantity 1 include?
Order quantity 1 means one full reel containing 2,000 SN74LVC244APWR components.
What should be checked before substituting another 74LVC244?
Check package, pinout, output-enable polarity, voltage range, 5 V input tolerance, IOFF behavior, propagation delay, output drive, and temperature grade.
Why does IOFF matter?
TI lists IOFF support for partial-power-down and live-insertion protection. This matters when one side of the system may be powered while another is off.
Which package is APWR?
The APWR orderable suffix corresponds to the TSSOP-20 package and tape-and-reel supply format for SMT assembly.
Where can I find the datasheet?
Use the attached Product Specification PDF for SN74LVC244A timing, output drive, input conditions, package data, and bus-interface guidance.
