SEMICONDUCTOR TECHNICAL DATA
Dual Binary to 1-4 Decoder (Low)
The MC10H171 is a binary coded 2 line to dual 4 line decoder with selected
outputs low. With either E0 or E1 high, the corresponding selected 4 outputs are high. The common enable E, when high, forces all outputs high.
•Propagation Delay, 2 ns Typical
•Power Dissipation 325 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.
