SEMICONDUCTOR TECHNICAL DATA
8-Input Priority Encoder
The MC10H165 is an 8–Input Priority Encoder. This 10H part is a
functional/pinout duplication of the standard MECL 10K family part, with 100%
improvement in propagation delay, and no increases in power–
supply current.
• Propagation Delay, Data–to–Output, 2.2 ns 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 Ifpm is maintained. Outputs are terminated through a
50–ohm resistor to –2.0 volts.
