LT1134AISW#PBF

LT1134AISW#PBF is an advanced low-power 5V RS232 driver/receiver with small capacitors. It features special bipolar construction techniques that protect the drivers and receivers beyond the fault conditions stipulated for RS232. Driver outputs and receiver inputs can be shorted to ±30V without damaging the device or the power supply generator. In addition, the RS232 I/O pins are resilient to multiple ±10kV ESD strikes. An advanced driver output stage operates up to 250kbaud while driving heavy capacitive loads. The DRIVER DISABLE pin disables the drivers and the charge pump, and the ON/active-low OFF pin shuts down all circuitry. While shut down, the drivers and receivers assume high-impedance output states.

• CMOS comparable low power
• Easy PC layout: flowthrough architecture, rugged bipolar design: absolutely no latchup
• Outputs assume a high impedance state when off or powered down
• Improved protection: RS232 I/O lines can be forced to ±30V without damage
• Output overvoltage does not force current back into supplies
• 3 drivers, 5 receivers, 4 capacitors
• Slew rate is 15V/µs typ at RL=3k, CL=51pF, TA=25°C
• Oscillator frequency is 130kHz typ at TA=25°C
• 24-lead plastic SO wide package
• Operating temperature range from -40° to 85°C
