Moreover, having the • Power-Down Feature: (THS3095 Only) ability to handle large voltage swings driving into high-resistance and high-capacitance loads while maintaining good settling time performance makes • High-Voltage Arbitrary Waveform the devices ideal for Pin driver and PowerFET driver • Power FET Driver applications. • Pin Driver The THS3091 and THS3095 are offered in an 8-pin • VDSL Line Driver SOIC (D), and the 8-pin SOIC (DDA) packages with PowerPAD™.
