GX214A

GX214A Monolithic 4x1 Video Multiplexer DATA SHEET FEATURES low cost differential gain at 3.58 MHz, 0.05% max. differential phase at 3.58 MHz, 0.05 deg. max. off-isolation better than 90 dB at 10 MHz all hostile crosstalk at 3.58 MHz, 75 dB typ. (RIN= 75 Ω) make-before-break switching FUNCTIONAL BLOCK DIAGRAM IN 0 IN 1 IN 2 IN 3 X X X X 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 compatible input logic levels.
