CIRCUIT DESCRIPTION
The GX214A is a low cost 4x1 video multiplexer containing
four analog video switches and a 2 to 4 decoder. A Chip
Select input allows paralleled GX214As to be operated in
a switching matrix.
The GX214A represents a fully buffered, unilateral transmission
path when enabled. When disabled, the output is high
impedance.
The device operates from
±
7.5 V to
±
9.5 V supplies with
TTL and 5 V CMOS compatible input logic levels.
APPLICATIONS
• CATV and CCTV systems
• low cost video routing
