Product details

3.3 V bus buffer with strong drive

The SN74LVTH244ANS: The part delivers 32 mA source and 64 mA sink per output.

Output drive and bus loading

The 32 mA high-level and 64 mA low-level output current ratings are the standout spec here — most 3.3 V buffers in the 74LVC or 74AHCT families top out around 24 mA. That extra margin means the SN74LVTH244ANS can drive a higher fan-out or longer PCB trace without signal degradation, which matters for clock distribution or memory-interface buffers where setup/hold margins are tight. The 3-state outputs allow multiple devices to share a bus without contention, controlled by the output-enable pins (active-low per the 244 function).

Package and footprint

Housed in a 20-SOIC (0.209", 5.30 mm width) package, the SN74LVTH244ANS uses the standard 20-SO body width.

Frequently asked questions

What is the output drive capability of SN74LVTH244ANS?

Each output can source 32 mA and sink 64 mA, which is higher than typical 3.3 V buffers — useful for driving high-fanout buses or long traces.

What are the alternatives to SN74LVTH244ANS?

The SN74LVTH16245ADGVR is a 16-bit transceiver in the same 74LVTH family with similar 32 mA drive, but it offers bidirectional data flow and a different pinout (48-pin TSSOP). For a smaller 2-bit buffer with Schmitt-trigger inputs, the SN74LVC2G17QDCKRQ1 (automotive grade) is an option, though its output drive is lower.
