DS1679 - Hex TRI-STATEE TTL to MOS Drivers

Download the DS1679 datasheet PDF. This datasheet also covers the DS1649 variant, as both devices belong to the same hex tri-statee ttl to mos drivers family and are provided as variant models within a single manufacturer datasheet.

General Description

The DS1649 DS3649 and DS1679 DS3679 are Hex TRI-STATE MOS drivers with outputs designed to drive large capacitive loads up to 500 pF associated with MOS memory systems PNP input transistors are employed to reduce input currents allowing the large fan-out to these drivers needed in memory systems The
