It is pin compa tible with industry standard 74F/FCT/LS/AS/ALS257 logic devices. Its control inputs were not just designed to meet standard and LV CMOS/TTL logic level, but also designed to be used with most advanced chipset or S OC with 1.8V control inputs and outputs. It built in undershoot clamping diodes on all control inputs and switch in puts that results in robust and reliable switching.

SV73257A www.savitech-ic.com Function Diagram Absolute Maximum Ratings Parameter Value Unit VCC to GND, Supply Voltage, 7 V Input Voltage GND - 0.3 to (V CC) +0.3 V Storage Temperature Range -65 to +150 °C Continuous current through V CC or GND 100 mA ESD Susceptibility: HBM > 8000 V ESD Susceptibility: MM 400 V Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. T his is a stress rating only; functional operation of the device at these or any other conditions above those indica ted in the operational section of this specification is not imp lied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Caution This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SAVITECH rec ommends that all integrated circuits be handled with appropri ate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not t o meet its published specifications.

For max. or min. conditions, use appropriate value s pecified under Electrical Characteristics for the applicable device type. 2. Guaranteed by design. 3. The switch contributes no propagation delay other tha n the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagation delay to the system. Propagation delay of the switch when used in a system is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side.
