400MHz Multiplexing Amplifier
ISL59420
The ISL59420 is a 420MHz bandwidth 2:1 multiplexing
amplifier designed primarily for video switching. This Mux-amp
has user-settable gain and also feature a high speed three-state
function to enable the output of multiple devices to be wired
together. All logic inputs have pull-downs to ground and may be
left floating. The ENABLE pin, when pulled high, sets the
ISL59420 to the low current power-down mode for power
sensitive applications - consuming just 5mW.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTE:
4. If an input signal is applied before the supplies are powered up, the input current must be limited to these maximum values.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise
noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
Electrical Specifications V+ = +5V, V- = -5V, GND = 0V, TA = 25°C, RL = 500Ω to GND unless otherwise specified.
