SWITCHING WAVEFORMS FOR VARIOUS ANALOG INPUT VOLTAGES Application Information Logic Compatibility The HI-201HS is TTL compatible. Its logic inputs (pins 1, 8, 9, and 16) are designed to react to digital inputs which exceed a fixed, internally generated TTL switching threshold. The HI-201HS can also be driven with CMOS logic (0V15V), although the switch performance with CMOS logic will be inferior to that with TTL logic (0V-5V). The logic input design of the HI-201HS is largely responsible for its fast switching speed. It is a design which features a unique input stage consisting of complementary vertical PNP and NPN bipolar transistors. This design differs from that of the standard HI-201 product where the logic inputs are MOS transistors. Although the new logic design enhances the switching speed performance, it also increases the logic input leakage currents. Therefore, the HI-201HS will exhibit larger digital input leakage currents in comparison to the standard HI-201 product. Charge Injection Charge injection is the charge transferred, through the internal gate-to-channel capacitances, from the digital logic input to the analog output. To optimize charge injection performance for the HI-201HS, it is advisable to provide a TTL logic input with fast rise and fall times. If the power supplies are reduced from ±15V, charge injection will become increasingly dependent upon the digital input frequency. Increased logic input frequency will result in larger output error due to charge injection. Power Supply Considerations The electrical characteristics specified in this data sheet are guaranteed for power supplies VS = ±15V. Power supply voltages less than ±15V will result in reduced switch performance. The following information is intended as a design aid only. POWER SUPPLY VOLTAGES ±12 ≤ VS ≤ ±15V SWITCH PERFORMANCE Minimal Variation VS < ±12V Parametric variation becomes increasingly large (increased ON resistance, longer switching times). VS < ±10V Not Recommended. VS > ±16V Not Recommended. Single Supply The switch operation of the HI-201HS is dependent upon an internally generated switching threshold voltage optimized for ±15V power supplies. The HI-201HS does not provide the necessary internal switching threshold in a single supply system. Therefore, if single supply operation is required, the HI-300 series of switches is recommended. The HI-300 series will remain operational to a minimum +5V single supply. Switch performance will degrade as power supply voltage is reduced from optimum levels (±15V). So it is recommended that a single supply design be thoroughly evaluated to ensure that the switch will meet the requirements of the application.
