Dual 4 to 1 Multiplexer

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.

• Propagation Delay, 1.5 ns Typical

• Power Dissipation, 305 mW 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 Iinear fpm is maintained. Outputs are terminated

through a 50–ohm resistor to –2.0 volts.
