- 1ku List Price
- Starting From $5.02
Overview
- Operates from a Single 5V Supply
- Low Supply Current: ICC = 220µA
- ICC = 0.2µA in Shutdown Mode
- ESD Protection Over ±10kV
- Uses Small Capacitors: 0.1µF
- Operates to 120kBaud
- Output Overvoltage Does Not Force Current Back into Supplies
- RS232 I/O Lines Can Be Forced to ±25V Without Damage
- Pin Compatible with LT1180A
The LTC1382 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.
The LTC1382 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 120kbaud with a 2500pF, 3k Ω load. Both driver outputs and receiver inputs can be forced to ±25V without damage and can survive multiple ±10kV ESD strikes.
