transistor for reset switch

i have a display and an mp3 decoder chip that need to be reset before data can be sent to them, is it ok to use a single pin off the propellor with a transistor, the reset pins are opposites though, one needs to be pulled high the other low, (this means 2 transistors right?)·is there any transistor that would work best, also when the propellor boots up from eeprom, does it reset or does it just start if it resets can the transistor be rigged up to that,

    you can write code to toggle a pin on boot up. use the following picture to make an inverter with 1 transister

    If you tie the ic requiring high reset to the ic and the one requiring low reset to the output you can reset both by setting the output to 1 on startup.
