LTC1383IS#PBF

LTC1383 is an ultra-low power 2-driver/2-receiver RS232 transceiver that operates from a single 5V supply. The charge pump requires only four space saving 0.1µF capacitors. The supply current (ICC) of the transceiver is only 220µA with driver outputs unloaded. It is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate upto 120Kbaud with a 2500pF, 3Kohm load. Both driver outputs and receiver inputs can be forced to ±25V without damage and can survive multiple ±10KV ESD strikes. It is widely used in application such as notebook computers, palmtop computers etc.

• Output overvoltage does not force current back into supplies
• RS232 I/O lines can be forced to ±25V without damage
• Pin compatible with LT1181A and MAX232A
• Slew rate is 8V/µs typical at (RL = 3K, CL = 51pF)
• Input resistance is 5Kohm typical at (-10V ≤ VIN ≤ 10V)
• Output voltage is 0.2V typical at (output low, IOUT = -1.6mA, VCC = 5V)
• Operating temperature is -40°C to 85°C
• Package style is 16-lead plastic NSOIC
