AMD AmZ8148
The AmZ8148 Address Decoder combines a three-line to eightline decoder with four qualifying enable inputs (two active HIGH and two active LOW) and the acknowledge output required for "ready" or "wait state" control of all popular MOS microprocessors. The acknowledge output, ACK, is active LOW and responds to the combination of all enables and an acknowledge active, input command. The eight chip select outputs are individually active LOW in response to the combination of all enables active and the corresponding 3-bit input code at the S inputs.| Part No. | AmZ8148 |
