Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

1. 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 lfpm is maintained.
Outputs are terminated through a 50 W resistor to 2.0 V.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.

8INPUT PRIORITY ENCODER
The MC10H165 is a device designed to encode eight
inputs to a binary coded output. The output code is that of the
highest order input. Any input of lower priority is ignored.
Each output incorporates a latch allowing synchronous
operation. When the clock is low the outputs follow the
inputs and latch when the clock goes high. This device is
very useful for a variety of applications in checking system
status in control processors, peripheral controllers, and
testing systems.
The input is active when high, (e.g., the three binary
outputs are low when input D0 is high). The Q3 output is
high when any input is high. This allows direct extension
into another priority encoder when more than eight inputs
are necessary. The MC10H165 can also be used to develop
binary codes from random logic inputs, for addressing
ROMs, RAMs, or for multiplexing data.
