• Product Introduction

LT1130AISW

Advanced low-power 5V RS-232 driver/receiver with small capacitors (including via LT1141 LT1130)

peculiarity

• ESD protection over ± 10KV (± 15kV IEC-1000-4-2 for LT1133A, LT1137A and LT1141A)
• Use small capacitors: 0.1μF, 0.2μF
• The 1μA supply current is off
• R L = 3K, CL = 2500pF 120kbaud operation
• R L = 3K, C L = 1000PF 250kbaud operation
• CMOS is relatively low-power
• Easy PC layout: flow through architecture
• Rugged bipolar design: absolutely no latching
• The output assumes a high impedance state when turned off or powered off
• Perfect protection: RS-232 I/O wire forced ± 30V without damage
• The output overvoltage does not force the supply current to flow back
• Available in SO and SSOP packages

description

™LT 1130A/LT1140A RS232 Driver/Receiver features a special bipolar type of construction technology that protects the driver and receiver beyond fault conditions for RS232. Driver output and receiver input, can short-circuit up to ± 30V without damaging the device or power generator. In addition, the RS232 I/O pins are resilient to multiple ± 10kV ESD shock. An advanced driver output stage operates at up to 250kbaud while driving large capacitive loads. The power supply current is usually 12 mA, which is the competitiveness of CMOS devices. Several members of the family, including flexible business model control. Driver Disable Pin Disable the ON/OFF pins of the driver and charge pump, shutting down all circuitry. Although off, the driver and receive assume a high impedance output state.
