Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Reset Output, Open-Drain or Push-Pull, Active-Low.
RESET
changes from HIGH to LOW when V
CC
drops below the
selected reset threshold or
MR
is pulled low.
RESET
remains
LOW for the reset timeout period after V
CC
exceeds the device
reset threshold and
MR
is released high.
Reset Output, Push-Pull, Active-High. RESET changes from
LOW to HIGH when the V
CC
input drops below the selected
reset threshold or
MR
is pulled low. RESET remains HIGH for
the reset timeout period after V
CC
exceeds the device reset
threshold and
MR
is released high.
Active-Low Manual Reset Input. Internal 20kΩ pullup to V

Pull LOW to force a reset. Reset remains active as long as
MR
is
LOW and for the reset timeout period after
MR
goes HIGH.

RESET-IN
Adjustable Reset Threshold Input. High-impedance input for reset comparator. Connect
this pin to an external resistive-divider network to set the reset threshold voltage; the
typical threshold is 444mV. Reset is asserted when RESET-IN is below the threshold (V
CC
is not monitored).
Supply Voltage (1.1V to 3.3V)
Ground
Reset Output, Push-Pull, Active-High. RESET changes from LOW to HIGH when the
RESET-IN input drops below the typical reset threshold (444mV). RESET remains HIGH for
the reset timeout period after RESET-IN exceeds the reset threshold.
Reset Output, Open-Drain or Push-Pull, Active-Low.
RESET
changes from HIGH to LOW
when RESET-IN drops below the typical reset threshold (444mV).
RESET
remains LOW for
the reset timeout period after RESET-IN exceeds the reset threshold.

台积电不愧是晶圆代工的绝对王者，2017年销售再次称霸，营收足足是第二名的五倍。与此同时，陆厂急起直追，华虹集团(Huahong Group)的成长率傲视全球主要业者。 IC Insights 24日新闻稿称，2017年晶圆代工市场由台积电夺冠，销售年增9%至322亿美元，遥遥领先晶圆代工二哥格芯(GlobalFoundries，原格罗方德)。台积电去年销售是格芯的五倍、更是第五名陆厂中芯国...[详细]
据外媒报道，现代摩比斯于2018年4月24日宣称，该公司最近研发了一款电控悬架部件——电动主动式翻滚抑制系统（electrical Active Roll Stabilization，eARS）。 eARS是一款车用部件，当车辆快速转向并因道路不平而受到冲击时，可缓解离心力引起的车身倾斜，有助于使行驶中车辆车身的水平倾斜起到平衡作用。该项新技术替代了早前的平衡杆（stabilizer bar）...[详细]
近年来，中国厂家涌入面板行业，导致国际液晶显示屏价格一跌再跌。受此打击，行业巨头韩国LG Display公司遭创严重，昨日，他们公布了6年来的首次运营亏损。 由于行业技术革新，LG Display必须投入更多资金用于兴建OLED面板的生产线，也是他们利润下滑的一大原因。 LG Display CFO Don Kim表示：“市场变化的速度远超我们的预期。我们将采取有效、灵活的手段对资本指出...[详细]
