FHP3194
FHP3194 is 4:1 High Speed Multiplexer manufactured by Fairchild Semiconductor.
Features at ±5V - 0.1d B gain flatness to 155MHz - 7.5ns channel switching time - 0.02%/0.03° differential gain/phase error - 335MHz full power -3d B bandwidth at G=2 - 1600V/µs slew rate - 60m A output current (easily drives three video loads) - 70d B channel to channel isolation - 13m A supply current - 4m A supply current in disable mode - 3m A supply current in shutdown mode - Fully specified at ±5V supplies - Lead (Pb) - free SOIC-14 and TSSOP-14 packages Description The FHP3194 is a 4:1 analog multiplexer designed for high speed video applications. The output amplifier is a high-speed current feedback amplifier that offers stellar large signal performance of 335MHz -3d B bandwidth and 80MHz 0.1d B bandwidth. The gain of the output amplifier is selectable thru 2 external resistors (Rf and Rg), allowing further flexibility. The 2Vpp bandwidth performance, 1600V/µs slew rate, and 0.02% / 0.03° differential gain and phase exceed the requirements of high definition television (HDTV) and other multimedia applications. The output amplifier also provides ample output current to drive multiple video loads. Two address bits (A0 and A1) are used to select one of the four buffered inputs. The FHP3194 offers excellent 7.5ns switching times and better than 70d B channel isolation. The FHP3194 offers both shutdown and disable capability. During shutdown, the FHP3194 consumes only 3m A of supply current and provides maximum input to output isolation. During disable mode, only the output amplifier is disabled reducing output glitches and allowing for multiplexer expansion.
