The MC10123 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 MC10123 are “turned–off.” This eliminates discontinuities in the
characteristic impedance of the bus.
The VOH level is specified when driving a 25–ohm load terminated to –2.0
Vdc, the equivalent of a 50–ohm bus terminated at both ends. Although 25
ohms is the lowest characteristic impedance that can be driven by the
MC10123, higher impedance values may be used with this part. A typical
50–ohm bus is shown in Figure 1.
