DS9643

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 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 Connection Diagram 8-Lead DIP Truth Table Input L L H H Enable L H L H Output L L L H Top View Order Number DS9643N See NS Package Number N08E TL F 9646 – 1 C1995 National Semiconductor Corporation TL F 9646 RRD-B30M115 Printed in U S A Absolute Maximum Ratings (Note 1) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Storage Temperature Range b65 C to a150 C Operating Temperature Range 0 C to a70 C Lead Temperature Mo...
