Product details

What this 74LVTH transceiver does on the bus

The Texas Instruments SN74LVTH2952PW is a single-element, 8-bit non-inverting transceiver from the 74LVTH series, with 3-state outputs for shared bus applications. The output drive is rated at 32mA source and 64mA sink per channel, enough to drive heavily loaded parallel buses without external buffers.

Pin-compatible alternatives worth knowing

If you need a wider bus interface, the SN74LVTH16245ADGVR is a 16-bit (2-element) variant in the same 74LVTH series, also 2.7V–3.6V and 32mA drive, but in a 48-pin TSSOP package — a different footprint entirely.

Supply voltage and 5V compatibility

The SN74LVTH2952PW is specified for a 2.7V to 3.6V supply rail. It is not a 5V-tolerant device — feeding 5V into the supply or applying 5V logic levels to the inputs without level translation risks exceeding the absolute maximum ratings. For a 3.3V system, it works cleanly; if the other side of the bus runs at 5V, add an external level shifter or use a 5V-tolerant family like 74ABT.

Frequently asked questions

What are the alternatives to SN74LVTH2952PW?

For a wider 16-bit bus, consider the SN74LVTH16245ADGVR (same series, 2.7V–3.6V, 32mA drive, 48-TSSOP). For legacy 5V systems, the SN74ABT2245DW (4.5V supply, 32mA drive, commercial temp) is a functional alternative but not pin-compatible. The SN74LS645-1N is a through-hole 74LS part with lower drive and 0°C–70°C range.

Can SN74LVTH2952PW be used with a 3.3V supply?

Yes, 3.3V is within the specified 2.7V to 3.6V supply range, making it the intended operating point for this transceiver.
