| TECHNICAL DATA AUTOMOTIVE DIGITAL CLOCK IC DESCRIPTION IN7100 is a automotive digital clock, CMOS LSI. It drives fluorescent indicator panel directly. It can be driven by a 4.194304 MHz crystal oscillator or an external clock signal (1024 Hz). It has 4-ways display brightness control function and its display format is 12 hours. FEATURES * 4.194304 MHz crystal oscillator * 4-ways display brightness control ( Segment signal duty: 1, 1/4, 1/8, 1/16 ) * Hours and Minutes Setting * 30 seconds auto correction * 1024 Hz external clock drive * 1024 Hz SIGNAL output * Segment Output: P-channel open drain * 40 DIP package MS-011AC ABSOLUTE MAXIMUM RATINGS (Ta = 25 C) Parameter Power Supply Voltage Input Voltage Output Voltage Operating Temperature Storage Temperature Symbol VDD - VSS VIN VOUT Ta TSTG Specification - 0.5 ~ + 8.0 40 1 IN7100 DIP-40 Unit V V V C C VSS - 0.3 ~ VDD + 0.3 VDD - 30 ~ VDD + 0.3 - 40 ~ + 85 - 55 ~ + 125 DC CHARACTERISTICS (Ta=25C, RH70%, CD=CG=15pF, Xtal=4.194304MHz) Characteristic Power Supply Voltage Power Supply Current Leakage Current (1) High Level Output Current (2) High Level Output Current (3) Low Level Output Current (4) High Level Input Current (5) High Level Input Current External Clock Duty OSC.
