MC10H123
Triple 4−3−3−Input Bus
Driver
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 V_OL = −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.
The V_OH level is specified when driving a 25 W load terminated to
−2.0 Vdc, the equivalent of a 50 W bus terminated at both ends.
Although 25 W is the lowest characteristic impedance that can be
driven by the MC10H123, higher impedance values may be used with
this part. A typical 50 W bus is shown in Figure 3.
