Product Summary
The SN65HVD33DR is a 3-state differential line driver and differential-input line receiver that operate with 3.3V power supply. Each driver and receiver has separate input and output pins for full-duplex bus communication designs. The SN65HVD33DR is designed for RS-422 and RS-485 data transmission over cable lengths of up to 1500 meters. The SN65HVD33DR has active-high driver enables and active-low receiver enables. A low, less than 1mA, standby current can be achieved by disabling both the driver and receiver.
Parametrics
SN65HVD33DR absolute maximum ratings: (1)Supply voltage range, Vcc: –0.3V to 6V; (2)Voltage range at any bus terminal (A, B, Y, Z), V(A), V(B), V(Y), V(Z): –9V to 14V; (3)Voltage input, transient pulse through 100 Ω. See Figure 12 (A, B, Y, Z), V(TRANS): –50 to 50V; (4)Input voltage range (D, DE, RE), VI: -0.5V to 7V; (5)Output current (receiver output only, R), IO: 11mA.
Features
SN65HVD33DR features: (1)1/8 Unit-Load Option Available (Up to 256 Nodes on the Bus); (2)Bus-Pin ESD Protection Exceeds 15 kV HBM ; (3)Optional Driver Output Transition Times for Signaling Rates of 1 Mbps, 5 Mbps and 26 Mbps ; (4)Low-Current Standby Mode: < 1 mA ; (5)Glitch-Free Power-Up and Power-Down Protection for Hot-Plugging Applications; (6)5V Tolerant Inputs ; (7)Bus Idle, Open, and Short Circuit Failsafe; (8)Driver Current Limiting and Thermal Shutdown ; (9)Designed for RS-422 and RS-485 Networks ; (10)5V Devices available, SN65HVD50-55.
