产品信息
产品概述
MAX3243EEAI+ is a RS-232 transceiver with AutoShutdown. It is a 3V-powered EIA/TIA-232 and V.28/V.24 communications interface with automatic shutdown/wakeup features, high data rate capabilities, and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 air gap discharge, to ±8kV using IEC 1000-4-2 contact discharge, and to ±15kV using the human body model. It achieves a 1µA supply current with the AutoShutdown™ feature. This saves power without changes to the existing BIOS or operating system by entering low-power shutdown mode when the RS-232 cable is disconnected, or when the transmitters of the connected peripherals are off. Applications include notebook, subnotebook, and palmtop computers, cellular phones, battery-powered equipment, handheld equipment, peripherals, printers.
- Supply current (shutdown) is 1.0µA typ at active-low FORCEOFF=GND, all R-IN=GND, TA=+25°C
- Output voltage swing is ±5.4V typ, all transmitter outputs loaded with 3kohm to ground
- Output resistance is 10Mohm typ at VCC=V+=V-=0, TOUT=±2V
- Output short-circuit current is ±60mA maximum
- Output leakage current is ±25µA max at VOUT=±12V, VCC=0 or 3V to 5.5V, transmitters disabled
- Maximum data rate is 250kbps min at RL=3kohm, CL=1000pF, one transmitter switching
- Receiver propagation delay is 0.15µs typ at CL=150pF
- Transition-region slew rate is 30V/µs max at CL=150pF to1000pF
- 28 SSOP package
- Temperature range from -40°C to +85°C
