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 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.

The VOH 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.
