19
V+
Circuit 4
Positive power supply
22
ENABLE
Circuit 2
Device enable (active low) w/Internal pull-down resistor. A logic High puts device into
power-down mode with the only logic circuitry active. All logic states are preserved post
power-down. This state is not recommended for logic control where more than one MUX-
amp share the same video output line.
23
LE
Circuit 2
Device latch enable on the ISL59424. A logic high on LE will latch the last (S0, S1) logic
state. HIZ and ENABLE functions are not latched with the LE pin.
21
HIZ
Circuit 2
Output disable (active high) w/internal pull-down resistor. A logic high, puts the outputs in
a high impedance state. Use this state to control logic when more than one MUX-amp
share the same video output line.
