Product details

What the 64 mA low-side drive buys you on a loaded bus

The SN74ABT244ANSR is a non-inverting buffer from TI's 74ABT series, with two 4-bit elements and 3-state outputs. Output drive is 32 mA high, 64 mA low.

5 V only — plan your voltage rails accordingly

Supply range is 4.5 V to 5.5 V, so this is a pure 5 V logic part. No 3.3 V compatibility on the inputs or outputs — if your design has a mixed-voltage bus, you will need a level translator or a different buffer from the 74LVC or 74AVC families. The industrial temperature grade of -40°C to 85°C covers most factory-floor and outdoor telecom enclosures but stops short of automotive under-hood or engine-bay environments.

20-SOIC footprint — what fits on the board

Housed in a 20-SOIC package with a 5.30 mm body width. The supplier device package is designated 20-SO. Surface-mount only.

Frequently asked questions

Is SN74ABT244ANSR RoHS compliant?

Yes, it is ROHS3 Compliant per TI's listing.

What are the equivalent parts for SN74ABT244ANSR?

The closest functional peer in the same 74ABT family is the SN74ABT2245DW, an 8-bit transceiver (non-inverting) with the same 4.5 V to 5.5 V supply and 32 mA output drive. It differs in being a single-element transceiver rather than a dual-element buffer, so direction-control pins replace the dual-enable scheme. For a 3.3 V system, the SN74LVTH16245ADGVR is a 16-bit transceiver in the 74LVTH family.
