Cannot find data sheet, any magician around to help, please ?

Hi.
Trying to find the data sheet for Texas Instruments integrated circuit marked
(TI logo) 58FXT7K
HC14M

Gets data from an Analog Devices DSP chip and drives data to the gates of a 3 phase motor speed controller module by International Rectifier (IRAMS10UP60A)* from a front-load clotheswasher donor.

Control panel ---> 4 data lines ---> DSP---> T.I. chip ---> 6 gate drive lines to IR chip ----> 3 phase motor
The intention is to modify the use to manual motor speed control with potentiometers, if possible.
* I do have its data sheet

Are you sure it's not just a 74HC14M?

Thanks, tunedwolf. It crossed my mind, but did not follow trough considering being a '74...
Will investigate, fits well being a hex inverter !
