DS9643 Datasheet Dual Ttl To Mos/ccd Driver

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: DS9643 Dual TTL to MOS CCD Driver April 1990 DS9643 Dual TTL to MOS CCD Driver.

General Description

The DS9643 is a dual positive logic ‘‘AND’’ TTL-to-MOS driver The DS9643 is a functional replacement for the SN75322 with one important exception the two external PNP transistors are no longer needed for operation The DS9643 is also a functional replacement for the 75363 with the important exception that the VCC3 supply is not needed The lead connections normally used for the external PNP transistors are purposely not internally connected to the DS9643

Key Features
