MCHC8 -to-8 Line Decoder The MCHC8 is an advanced high speed CMOS to 8 decoder fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. When the device is enabled, three Binary Select inputs ( A) determine which one of the outputs (Y0 Y) will go Low. When enable input E is held Low or either E or E is held High, decoding function is inhibited and all outputs go high. E, E, and E inputs are provided to ease cascade connection and for use as an address decoder for memory systems. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to, allowing the interface of systems to systems. High Speed: t PD =.ns (Typ) at CC = Low Power Dissipation: I CC = μa (Max) at T A = C High Noise Immunity: NIH = NIL = 8% CC Power Down Protection Provided on Inputs Balanced Propagation Delays Designed for to.

Derating SOIC Packages: mw/ C from to C TSSOP Package:. mw/ C from to C This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation, in and out should be constrained to the range GND ( in or out ) CC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or CC ). Unused outputs must be left open.
