Product details

Active 3.3V bus transceiver — 8-bit, 3-state, 20-SOIC

The SN74LVTH245ANS: Output drive is rated 32 mA source and 64 mA sink, enough to drive a heavily loaded parallel bus without external buffers.

20-SOIC footprint and supply rails

Packaged in a 20-SOIC (0.209-inch body width, 5.30 mm), the SN74LVTH245ANS mounts on standard surface-mount pads and is supplied in tube. The supplier device package is 20-SO. Single-element, 8-bit-per-element configuration with a single 2.7V–3.6V supply rail — no separate I/O or core voltage needed. The 3-state output allows multiple transceivers to share a bus without contention.

For a spare-parts storeroom, this part is still a standard catalog item; no last-time-buy pressure.

Frequently asked questions

Will SN74LVTH245ANS drop into a board designed for SN74ABT2245DW?

Both are 20-SOIC 8-bit non-inverting transceivers with 3-state outputs, but the SN74ABT2245DW runs on a 4.5V supply while the SN74LVTH245ANS is rated for 2.7V–3.6V. If the board's VCC rail is 3.3V, the LVTH part is a direct drop-in; if the rail is 5V, the LVTH part exceeds its abs-max and will not work without a supply change.
