SRPS026A - JANUARY 1985 - REVISED NOVEMBER 1995
The TIB82S167BC is a TTL field-programmable state machine of the Mealy type. This state machine (logic sequencer) contains 48 product terms (AND terms) and 12 pairs of sum terms (OR terms). The product and sum terms are used to control the 8-bit internal state register and the 4-bit output register.
The outputs of the internal state register (P0-P7) are fed back and combined with the 14 inputs (I0-I13) to form the AND array. In addition the first two bits of the internal state register (P0-P1) are brought off-chip to allow the output register to be extended to 6 bits if desired. A single sum term is complemented and fed back to the AND array, which allows any of the product terms to be summed, complemented, and used as inputs to the AND array.
The state and output registers are positive-edge- triggered S/R flip-flops. These registers are unconditionally preset high during power up. PRE/OE\ can be used as PRE to preset both registers or, by blowing the proper fuse, be converted to an output control function, OE\.
The TIB82S167BC is characterized for operation from 0°C to 75°C.
