SEMICONDUCTOR TECHNICAL DATA
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.

Pin assignment is for Dual–in–Line Package.
Each MECL 10H series circuit has been designed to meet the dc specifications shown in the test table,
afterthermalequilibriumhasbeenestablished.Thecircuitisinatestsocketormountedonaprintedcircuit
board and transverse air flow greater than 500 Ifpm is maintained. Outputs are terminated through a
50–ohm resistor to –2.0 volts.
For PLCC pin assignment, see the Pin Conversion
Tables on page 6–11 of the Motorola MECL Data
Book (DL122/D).
