Triple 4-3-3-Input Bus Driver
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–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
MC10H123, higher impedance values may be used with this part. A typical
50–ohm bus is shown in Figure 1.
• Propagation Delay, 1.5 ns Typical
• Improved Noise Margin 150 mV (Over Operating Voltage and
Temperature Range)
• Voltage Compensated
• MECL 10K–Compatible

NOTE:
Each MECL 10H series circuit has been designed to meet the dc specifications shown in the test table,
after thermal equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit
board and transverse air flow greater than 500 Ifpm is maintained. Outputs are terminated through a
50–ohm resistor to –2.1 volts.
