ICL3217集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書PDF中文資料

The Intersil ICL32X7 devices are 3.0V 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. 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 ICL3217’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 5.0V systems, and 5.0V only systems, and is a lower power, pin-for-pin replacement for ‘207 and ‘237 type devices.
