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.

NOTES:
1. When VBB is used as the reference voltage.
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.

The MC10H115 does not have internal–input pull–
