IDT IDT39C09B
The IDT39C09/11 devices are high-speed, 4-bit address sequencers intended for controlling the sequence of microinstructions located in the microprogram memory. They are fully cascadable and can be expanded to any increment of 4 bits. The IDT39C09s can select an address from any four sources: 1) external direct inputs (D); 2) external data from the R inputs, stored in an internal register; 3) a 9-word deep push-pop stack; or 4) a program counter register.| Part No. | IDT39C09B |
