DS9643 Dual TTL to MOS/CCD Driver General Description Features 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.

They are not meant to imply that the devices should be operated at these limits. The tables of ‘‘Electrical Characteristics’’ provide conditions for actual device operation. Note 2: Unless otherwise specified Min/Max limits apply across the 0§ C to a 70§ C range for the DS9643. All typicals are given for VCC1 e 5V, VCC2 e 12V and TA e 25§ C. Note 3: All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are reference to ground unless otherwise specified. 2 Switching Characteristics VCC1 e 5.0V, VCC2 e 12V, TA e 25§ C Symbol Parameter tDLH Delay Time tDHL Delay Time tTLH Rise Time tTHL Fall Time tTLH Rise Time tTHL Fall Time tPLHAb tPLHB tPHLAb tPHLB Skew between Outputs A and B Conditions CL e 300 pF RSERIES e 0 CL e 300 pF RSERIES e 10X CL e 300 pF Min Typ Max Units 5.0 9.0 17 ns 5.0 9.0 17 ns 6.0 11 17 ns 6.0 11 17 ns 8.0 14 20 ns 8.0 14 20 ns 0.5 ns TL/F/9646 – 2 FIGURE 1.
