Dual 4 to 1 Multiplexer
MC10H174
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.
Pin assignment is for Dual–in–Line Package.
For PLCC pin assignment, see the Pin Conversion
Tables on page 6–11 of the Motorola MECL Data
Book (DL122/D).
