Yes do a search for "digital transistor", typically a single npn transistor
with a base-emitter resistor and a series base resistor to the outside
world. Designed for exactly this sort of use. All this comes in a SOT-23
package IIRC.

Made by Rohm and Vishay/Telefunken among others IIRC. If you have an RS
components CD look for digital transistor, I know they have carried them in
the past.
