Description
The MC10H123 is a triple 4−3−3−Input Bus Driver.
The MC10H123 consists of three NOR gates designed for bus driving applications on card or between cards. Output low logic levels are specified with VOL = −2.1 Vdc so that the bus may be terminated to −2.0 Vdc. The gate output, when low, appears as a high impedance to the bus, because the output emitter−followers of the MC10H123 are “turned−off.” This eliminates discontinuities in the characteristic impedance of the bus.
