Binary Coded Decimal to seven segment decoder - drivers have been designed and fabricated using $I^2L$ technology.
The chips are part of a digital watch system which is composed of counters and decoder-drivers.
A minimum power dissipation of 0.51mw and a minimum propagation delay time of 0.6usec have been obtained from the chips fabricated by standard $I^2L$ process with 10um minimum line width.
