DS9643
DS9643 is Dual TTL to MOS/CCD Driver manufactured by National Semiconductor.
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 patible inputs Y Separate drivers address inputs with mon strobe Y VOH and VOL patible with popular MOS RAMs Y Does not require external PNP transistors or VCC3 Y VOH minimum is VCC2 b 0 5V
