Advanced logic features

ABT and MultiByte™ products provide a solution for floating CMOS inputs different from the bus hold solution. They employ a feature called Input Disable which disables the input structure whenever the output is in the 3-State condition. When disabled, no current flows through the input structure from V_CC to ground. This allows inputs to float without the need for an input pull-up or pull-down resistor to V_CC or ground. This feature is included only on buffers and transceivers and not on parts with latches or flip-flops.

• Available on the following selected ABT 8-bit device types: 125, 126, 241, 2241, 244, 2244, 245, 2245, 541, 623, 657 (only on B I/O pins), 827, 861, and 863.
• Available on the following selected MultiByte^TM device types: 2241, 2244, 2245 2541, and 2623.
