SEMICONDUCTOR TECHNICAL DATA
The MC10H145 is a 16 x 4 bit register file. The active-low chip select allows
easy expansion.
The operating mode of the register file is controlled by the WE input. When
WE is “low” the device is in the write mode, the outputs are “low” and the data
present at D input is stored at the selected address, when WE is “high,” the
n
device is in the read mode — the data state at the selected location is present
at the Q outputs.

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
circuitboard and transverse air flow greater than 500 Ifpm is maintained. Outputs are terminated through
a 50-ohm resistor to –2.0 volts.
