Product Overview
LTC491 is a low power differential bus/line transceiver designed for multipoint data transmission standard RS485 applications with extended common mode range (12V to -7V). It also meets the requirements of RS422. The CMOS design offers significant power savings over its bipolar counterpart without sacrificing ruggedness against overload or ESD damage. The driver and receiver feature three-state outputs, with the driver outputs maintaining high impedance over the entire common mode range. Excessive power dissipation caused by bus contention or faults is prevented by a thermal shutdown circuit which forces the driver outputs into a high impedance state. The receiver has a fail safe feature which guarantees a high output state when the inputs are left open. It is widely used in application such as low power RS485/RS422 transceiver, level translator etc.
- Supply current is 300µA typical at (TA = 25°C, VCC = 5V ±5%)
- Designed for RS485 or RS422 applications, single 5V supply
- Power-up/-down glitch-free driver outputs permit live insertion or removal of package
- Driver maintains high impedance in three-state or with the power off
- Combined impedance of a driver output and receiver allows upto 32 transceivers on the bus
- Receiver input hysteresis is 70mV typical at (VCM = 0V, TA = 25°C, VCC = 5V ±5%)
- Pin compatible with the SN75180
- Operating temperature is -40°C to 85°C
- Package style is 14-lead plastic NSOIC
