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
Features
Y Satisfies CCD memory and delay line requirements Y Dual positive logic TTL to MOS driver Y Operates from standard bipolar and MOS supply volt-
ages Y High speed switching Y TTL and DTL compatible inputs Y Separate drivers address inputs with common strobe Y VOH and VOL compatible with popular MOS RAMs Y Does not require external
PNP transistors or VCC3 Y VOH minimum is VCC2 b 0 5V
