• 电压 (Voltage): 2.8Vdc—5.5Vdcl
• 电流 (Current):
Operating: Less than 3 mA maximum total current at 3.3V (for up to 3 tracks) while
card is being swiped
Sleeping: Less than 75 μ A maximum total current when no card is being swiped 1mA
• 速度范围 (Speed Range):3—100 in (7—250 cm)For the standard 75 to 210 bits per inch
(bpi) data densityl
• 操作环境: -40°C—75°C
二、优点：
• 可处理到三轨讯号，只要将4输出讯号VDD、VSS、DATA及 STROBE 接到 micro-controller 即可。
• Data buffer with Shift-Out
• 抗干扰 - 配合适切的 PCB layout，此ASIC能抗来至 PC monitors、cell phones、switching、
power supplies等干扰。
• 自动 Gain 控制，卡片读取从30%200% 的 International Standards Organization (ISO) 7811
amplitude standard。
