Product Summary
The SN75477DR is a dual peripheral driver designed for use in systems that require high current, high voltage, and fast switching times. The SN75477DR provide AND driver respectively. The SN75477DR have diode-clamped inputs as well as high-current, high-voltage clamp diodes on the outputs for inductive transient protection.
Parametrics
SN75477DR absolute maximum ratings: (1)Supply voltage, VCC (see Note 1): 7 V; (2)Input voltage, VI5.5 V; (3)Continuous output current (see Note 2)400 mA; (4)Peak output current: tw ≤ 10 ms, duty cycle ≤ 50%: 500 mA; (5)Peak output current: tw ≤ 30 ns, duty cycle ≤ 0.002%: 3 A; (6)Output clamp current, IOK: 400 mA; (7)Continuous total power dissipation: See Dissipation Rating Table; (8)Operating free-air temperature range, TA: 0°C to 70°C; (9)Storage temperature range, Tstg: –65°C to 150°C; (10)Lead temperature 1,6 mm (1/16 inch)from case for 10 seconds: 260°C.
Features
SN75477DR features: (1)Characterized for Use to 300 mA; (2)No Output Latch-Up at 55 V (After Conducting 300 mA); (3)High-Voltage Outputs (100 V Typ); (4)Output Clamp Diodes for Transient Suppression (300 mA, 70 V); (5)TTL- or MOS-Compatible Diode-Clamped Inputs; (6)pnp Transistor Inputs Reduce Input Current; (7)Standard Supply Voltage; (8)Suitable for Hammer-Driver Applications; (9)Plastic DIP (P)With Copper-Lead Frame Provides Cooler Operation and Improved Reliability.
