1 / 4 page  TLF5819 March 1995 DS3658 Quad High Current Peripheral Driver General Description The DS3658 quad peripheral driver is designed for those applications where low operating power high breakdown voltage high output current and low output ON voltage are required A unique input circuit combines TTL compatibility with high impedance In fact its extreme low input current allows it to be driven directly by a CMOS device The outputs are capable of sinking 600 mA each and offer a 70V breakdown However for inductive loads the output should be clamped to 35V or less to avoid latch-up during turn off (inductive fly back protectionrefer AN-213) An on- chip clamp diode capable of handling 800 mA is provided at each output for this purpose In addition the DS3658 incor- porates circuitry that guarantees glitch-free power up or down operation and a fail-safe feature which puts the output in a high impedance state when the input is open The molded package is specifically constructed to allow in- creased power dissipation over conventional packages The four ground pins are directly connected to the device chip with a special copper lead frame When the quad driver is soldered into a PC board the power rating of the device improves significantly Applications Y Relay drivers Y Lamp drivers Y Solenoid drivers Y Hammer drivers Y Stepping motor drivers Y Triac drivers Y LED drivers Y High current high voltage drivers Y Level translators Y Fiber optic LED drivers Features Y Single saturated transistor outputs Y Low standby power 10 mW typical Y High impedance TTL compatible inputs Y Outputs may be tied together for increased current ca- pacity Y High output current 600 mA per output 24A per package Y No output latch-up at 35V Y Low output ON voltage (350 mV typ 600 mA) Y High breakdown voltage (70V) Y Open collector outputs Y Output clamp diodes for inductive fly back protection Y NPN inputs for minimal input currents (1 mA typical) Y Low operating power Y Standard 5V power supply Y Power updown protection Y Fail safe operation Y 2W power package Y Pin-for-pin compatible with SN75437 Connection Diagram Dual-In-Line Package TLF5819 – 1 Top View Order Number DS3658N See NS Package Number N16E Truth Table IN EN OUT HH L LH Z HL Z LL Z H e High state L e Low state Z e High impedance state C1995 National Semiconductor Corporation RRD-B30M105Printed in U S A |
