Quad Line Receiver
MC10H115
The MC10H115 is a quad differential amplifier designed for use in sensing
differential signals over long lines. This 10H part is a functional/ pinout
duplication of the standard MECL 10K family part, with 100% improvement in
counting frequency and no increase in power–supply current.
The base bias supply (VBB) is made available at Pin 9 to make the device
useful as a Schmitt trigger, or in other applications where a stable reference
voltage is necessary. Active current sources provide the MC10H115 with
excellent common mode rejection. If any amplifier in a package is not used, one
input of that amplifier must be connected to VBB (Pin 9) to prevent upsetting the
current source bias network.

*VBB to be used to supply bias to the MC10H115 only
and bypassed (when used) with 0.01 µF to 0.1 µF
capacitor to ground (0 V). VBB can source < 1.0 mA.
The MC10H115 is designed to be used in sensing
differential signals over long lines. The bias supply
(VBB) is made available to make the device useful as a
Schmitt trigger, or in other applications where a stable
reference voltage is necessary.
Active current sources provide these receivers with
excellent common–mode noise rejection. If any
amplifier in a package is not used, one input of that
amplifier must be connected to VBB to prevent
unbalancing the current–source bias network.
The MC10H115 does not have internal–input pull–
down resistors. This provides high impedance to the
amplifier input and facilitates differential connections.
Applications:
• Low Level Receiver
• Voltage Level
• Schmitt Trigger

NOTES:
1. When VBB is used as the reference voltage.
2. Each MECL 10H series circuit has been designed to meet the 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 linear fpm is maintained. Outputs are terminated through a 50–ohm resistor to –2.0 volts.
3. Differential input not to exceed 1.0 Vdc.
4. 150 mVp–p differential input required to obtain full logic swing on output.
