SEMICONDUCTOR TECHNICAL DATA
The MC10H174 is a Dual 4–to–1 Multiplexer. This device is a functional/
pinout duplication of the standard MECL 10K part, with 100% improvement in
propagation delay and no increase in power supply current.

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 Iinear fpm is maintained. Outputs are terminated
through a 50–ohm resistor to –2.0 volts.

Tables on page 6–11 of the Motorola MECL Data
Book (DL122/D).
