The MC10H161 provides parallel decoding of a three bit binary word to one
of eight lines. The MC10H161 is useful in high–speed multiplexer/demultiplexer
applications.
The MC10H161 is designed to decode a three bit input word to one of eight
output lines. The MC10H161 output will be low when selected while all other
output are high. The enable inputs, when either or both are high, force all
outputs high.
The MC10H161 is a true parallel decoder. This eliminates unequal parallel
path delay times found in other decoder designs. These devices are ideally
suited for multiplexer/demultiplexer applications.
• Propagation Delay, 1.0 ns Typical
• Power Dissipation, 315 mW Typical (same as MECL 10K)
• 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.
