| GX4314L Low Power, Wideband 4 x 1 Video Multiplexer DATA SHEET FEATURES * low power; 12 mA ON current at 5 volts * low differential gain and phase * wide bandwidth; 100 MHz at -1 dB * 4.5 to 11 volt power supplies * available in 14 pin PDIP as well as 14 and 16 pin SOIC packaging * identical functions and pin outs to GX4314 with lower power DESCRIPTION The GX4314L is a low power, wideband video multiplexer implemented in bipolar technology. This device is characterized by excellent differential gain and phase in the enabled state, very high off-isolation in the disabled state and a fully buffered, unilateral signal path. Make-before-break switching assures virtually glitch-free switching. The GX4314L features a very high, nearly constant input impedance coupled with high output impedance in the disabled state. This allows multiple devices to be paralleled at the inputs and outputs without additional circuitry. Logic inputs are TTL and 5 V CMOS compatible, providing address and chip select functions. The operation of the device is described in the Truth Table below. The GX4314L offers pin for pin compatibility with Gennum's other 4x1 multipliers such as GX414, GX414A and GX434 with greatly improved bandwidth and slew rate. Since the GX4314L is capable of operation at 5 V supplies, system power can be reduced. X IN 2 X X OUTPUT FUNCTIONAL BLOCK DIAGRAM IN 0 X IN 1 X IN 3 Typically, the ON current is only 12 mA while the chip disabled current drops to less than 260 A. This feature allows the use of many devices in high density situations without excessive power dissipation.
