Product details

Buffer, non-inverting, 3-state — 32 mA / 64 mA drive in a 20-SSOP

The Texas Instruments SN74LVTH244ADB is a dual-element buffer with four bits per element, non-inverting logic, and 3-state outputs. The 32 mA source and 64 mA sink per output give it the fan-out to drive multiple loads or bus lines without external line drivers.

No special derating needed for most indoor or sheltered outdoor enclosures.

20-SSOP — compact surface-mount footprint

It is a drop-in footprint for designs already using SSOP-20 logic buffers.

Listed as Active by TI with ROHS3 compliance, this buffer is still in regular production.

Frequently asked questions

Is SN74LVTH244ADB RoHS compliant?

Yes — the part carries ROHS3 compliance status.

What is the closest functional equivalent to SN74LVTH244ADB?

The SN74LVTH16245ADGVR is a 16-bit transceiver in the same 74LVTH family, but it is a transceiver (bidirectional) with 8 bits per element, not a buffer. For a direct buffer replacement, stay within the 74LVTH244 family; the SN74LVTH244ADWR is the same buffer in a wider SOIC-20 package.
