All rights reserved. 24.Aug.2015 Rev.002 www.rohm.com TSZ22111・15・001 Absolute Maximum Ratings Parameter Symbol Limits Unit Supply Voltage VDD -0.3 to +7.0 V Input Voltage VIN VSS-0.3 to VDD+0.3 V Output Voltage Vo VSS-0.3 to VDD+0.3 V Total output current Σ Io 55 mA Operating Temperature Range Topr -25 to +85 °C Storage Temperature Tstg -55 to +125 °C Power Dissipation PD 0.76 (Note 1) W (Note 1) Derate by 7.6mW/°C when operating above TA=25°C (when mounted in ROHM’s standard board). Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. Recommended Operating Conditions (TA =25°C, VSS=0V) Parameter Symbol Limits Unit Condition Min Typ Max Power Supply Voltage VDD 2.7 - 5.5 V (Note 2) Output Voltage VO 0 - VDD V - Input rise time tr - - 1 µs applied to CLK,DATA,STB,CLB pins (Note 3) Input fall time tf - - 1 µs (Note 2) Set “L” to CLB pin during power up. Set ”H” to CLB pin after power is stable. When VDD become equal to or less than 2.2V, set “L” to CLB pin to clear the latch circuit. (Note 3) The input signal transition should be linear. Noise shouldn’t be on these input pins as there is no hysteresis countermeasure on them. The length of power and ground lines should be as short as possible and the bypass capacitor should be as close to the IC as possible so that the ground noise caused by the current in its operation don’t cause any undesirable data errors. The rise and fall times had better be smaller than the specified limits. |
