DS55451/2/3/4, DS75451/2/3/4 Series Dual Peripheral Drivers General Description Features The DS7545X series of dual peripheral drivers is a family of versatile devices designed for use in systems that use TTL logic. Typical applications include high speed logic buffers, power drivers, relay drivers, lamp drivers, MOS drivers, bus drivers and memory drivers. The DS55451/DS75451, DS55452/DS75452, DS55453/ DS75453 and DS55454/DS75454 are dual peripheral AND, NAND, OR and NOR drivers, respectively, (positive logic) with the output of the logic gates internally connected to the bases of the NPN output transistors.

Except for ‘‘Operating Temperature Range’’ they are not meant to imply that the devices should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device operation. Note 2: Voltage values are with respect to network ground terminal unless otherwise specified. Note 3: The voltage between two emitters of a multiple-emitter transistor. Note 4: The maximum voltage which should be applied to any output when it is in the ‘‘OFF’’ state. Note 5: Both halves of these dual circuits may conduct rated current simultaneously; however, power dissipation averaged over a short time interval must fall within the continuous dissipation rating. Note 6: Unless otherwise specified min/max limits apply across the b 55§ C to a 125§ C temperature range for the DS55450 series and across the 0§ C to a 70§ C range for the DS7545X series. All typicals are given for VCC e a 5V and TA e 25§ C. Note 7: All currents into device pins shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted. All values shown as max or min on absolute value basis. 3 Truth Tables (H e high level, L e low level) DS55453/DS75453 DS55451/DS75451 A B Y A B Y L L H H L H L H L (ON State) L (ON State) L (ON State) H (OFF State) L L H H L H L H L (ON State) H (OFF State) H (OFF State) H (OFF State) DS55452/DS75452 DS55454/DS75454 A B Y A B Y L L H H L H L H H (OFF State) H (OFF State) H (OFF State) L (ON State) L L H H L H L H H (OFF State) L (ON State) L (ON State) L (ON State) Schematic Diagrams DS55451/DS75451 DS55453/DS75453 TL/F/5824 – 13 TL/F/5824–11 Resistor values shown are nominal.
