LINEAR INTEGRATED CIRCUIT
2×75Ω DRIVER IC WITH 3
INTERNAL CIRCUITS
ꢀ
DESCRIPTION
The UTC A7623 is a 75Ω driver-IC. It is a follower for
video signals. It can be directly coupled to the previous stage
because there is no internal bias at the input pin. When output
is short to earth the IC enters power-save mode.
SOP-8
ꢀ
FEATURES
* Triple channels.
* Can be directly coupled to the previous circuit.
* Each output can drive two loads (75Ω×2).
* Output short circuit protection.
*Pb-free plating product number: A7623L
