It is available both in 28-pin molded dual-in-line packages or as dice. The MM58342 is particularly suited for driving high voltage (35V max) vacuum fluorescent (VF) displays (e.g., a 20-digit alphanumeric or dot matrix display). Block Diagram These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
