Motorola MC10H165FNR2, MC10H165L, MC10H165FN, MC10H165P Datasheet
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.
• 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.

MC10H165
8–INPUT 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

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.
