Suitable Buffer IC's for Midi Out Circuit.

Hello..

I'm working on a Teensy based Midi device, and I'm looking for suitable buffer IC's for the Midi out circuit. Typically for prototyping I'd just use a 74HC14 inverter, and just double up on the inputs, but I'm potentially gonna have 8 Midi outputs, which would mean three 74HC14's.

I've been looking at the SN74LVC244A which has eight channels. Looks like it should do the job, but I'm not 100% sure:


Any other recommendations would be appreciated, or a second opinion on the suitably of the SN74LVC244A would be great. Needs to run on 3.3v.

TIA
 
Do you need the hysteresis that a 74HC14 provides? If so you might want to keep it as-is, if not, then consider the 74HC245/74LVC245 which has a more logical pinout for an octal buffer...
