LTC1382CSW#PBF

LTC1382CSW#PBF 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 transceiver operates in one of two modes, normal and shutdown. In the normal mode, ICC is only 220µA with the driver outputs unloaded. In the shutdown mode, the charge pump is turned off, the driver outputs are forced into three-state, both receivers are off and ICC drops to 0.2µA. It is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 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 used in applications such as notebook computers, palmtop computers.

• Operates from a single 5V supply, ESD protection over ±10kV
• Output overvoltage does not force current back into supplies
• RS232 I/O lines can be forced to ±25V without damage
• Pin compatible with LT1180A
• Output leakage current is ±10µA typical at (shutdown or VCC = 0V, VOUT = ±10V)
• VCC supply current is 0.22mA typical at (no load, 0°C to 70°C)
• Supply leakage current (VCC) is 0.2µA typical at (VCC = 5V, C1 = C2 = C3 = C4 = 0.1µF)
• Slew rate is 8V/µs typical at (RL = 3K, CL = 51pF)
• Driver propagation delay (TTL to RS232) is 2µs typical at (VCC = 5V, C1 = C2 = C3 = C4 = 0.1µF)
• Operating temperature range from 0°C to 70°C, 18-lead plastic SO package
