• Product introduction

LT1140ACSW

Advanced Low Power 5V RS - 232 Driver/Receiver with Small Capacitors (including LT1141 LT1130)

peculiarity

• ESD protection exceeds ±10KV（±IEC - 1000 - 4 - 2 at 15kV for LT1133A, LT1137A and LT1141A)
• Small capacitors used: 0.1μF, 0.2μF
• The 1μA supply current is turned off
• _RL =_3K，CL= 2500pF 120kbaud operation
• _RL =_3K，CL = 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 powered off or powered off
• Perfect protection: RS-232 I/O line forced ± 30V without damage
• Output overvoltage does not force the supply current to flow back
• Available in both SO and SSOP packages

description

™The LT 1130A/LT1140A RS232 Driver/Receive feature features special bipolar building technology that protects the driver beyond fault conditions and receives a range of regulations for RS232. Driver outputs and receiver inputs can be shorted to ± 30V without damaging the device or power generator. In addition, the RS232 I/O pins are resilient to multiple ± 10kV ESD shocks. An advanced driver output stage operates at frequencies up to 250kbaud while driving large capacitive loads. The supply current is typically 12 mA, which is competitive for CMOS devices. Several members of the series include flexible business model control. The driver disable pin disables the ON/OFF pins of the driver and charge pump, shutting down all circuitry. While off, the driver and receive assume a high impedance output state.
