OUTPUT
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 patible input logic levels. APPLICATIONS
- CATV and CCTV systems
- low cost video routing
