AMD AmZ8144
The AmZ8140 and AmZ8144 are octal buffers fabricated using advanced low-power Schottky technology. The 20-pin package provides improved printed circuit board density for use in memory address and clock driver applications. The AmZ8140 and AmZ8144 are specified at 48mA and 24mA output sink current.| Part No. | AmZ8144 |

DESCRIPTION
Three-state outputs are provided to drive bus lines directly. Four buffers are enabled from one common line and the other four from a second enable line. The AmZ8140 and AmZ8144 enables are of similar polarity for use as a unidirectional buffer in which both halves are enabled simultaneously. Improved noise rejection and high fan-out are provided by input hysteresis and low current PNP inputs.
