Quad 2-Input Multiplexer/

Latch

The MC10H173 is a quad 2–input multiplexer with latch. 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.

• Data Propagation Delay, 1.5 ns Typical

• Voltage Compensated

• Power Dissipation, 275 mW Typical

• MECL 10K–Compatible

• Improved Noise Margin 150 mV (over

operating voltage and temperature range)

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.
