® ISO-CMOS MT8814 8 x 12 Analog Switch Array Features Internal control latches and address decoder Short set-up and hold times Wide operating voltage: 4.5V to 13.2V 12Vpp analog signal capability R ON 65 Ω max. @ V DD=12V, 25°C ∆R ON ≤ 10 Ω @ V DD=12V, 25°C Full CMOS switch for low distortion Minimum feedthrough and crosstalk Separate analog and digital reference supplies Low power consumption ISO-CMOS technology ISSUE 2 November 1988 Ordering Information MT8814AC 40 Pin Ceramic DIP MT8814AE 40 Pin Plastic DIP MT8814AP 44 Pin PLCC -40° to 85°C Description The Mitel MT8814 is fabricated in MITEL’s ISOCMOS technology providing low power dissipation and high reliability. The device contains a 8 x 12 array of crosspoint switches along with a 7 to 96 line decoder and latch circuits. Any one of the 96 switches can be addressed by selecting the appropriate seven address bits. The selected switch can be turned on or off by applying a logical one or zero to the DATA input. VSS is the ground reference of the digital inputs. The range of the analog signal is from VDD to VEE. Chip Select (CS) allows the crosspoint array to be cascaded for matrix expansion.
