ICL3217E集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書(shū)PDF中文資料

The Intersil ICL32X7E devices are 3V to 5.5V powered RS-232 transmitters (five)/receivers (three) which meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, they provide ±15kV ESD protection (IEC61000-4-2 Air Gap) and ±15kV Human Body Model protection on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are ISDN Terminal Adaptors, PDAs, Palmtops, peripherals, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical. The ICL3217E’s efficient on-chip charge pumps, coupled with an automatic powerdown function, reduces the standby supply current to a 1μA trickle. Small footprint packaging, and the use of small, low value capacitors ensure board space savings as well. Data rates greater than 250kbps are guaranteed at worst case load conditions. This family is fully compatible with 3.3V-only systems, mixed 3.3V and 5V systems, and 5V-only systems, and is a lower power, pin-for-pin replacement for ‘207E and ‘237E type devices.
