bcd-to-seven-segment common cathode led decodes/drivers

the aip74hc/hct48 feature active-low outputs designed for driving common-anode leds or incandescent indicators directly. display patterns for bcd input counts above 9 are unique symbols to authenticate input conditions.

the aip74hc/hct48 incorporate automatic leading and/or trailing-edge zero-blanking control (rbi() andrbo()). lamp test (lt()) of these types may be performed at any time when thebi()/rbo() node is at a high level. the aip74hc/hct48 contain an overriding blanking input (bi()), which can be used to control the lamp intensity by pulsing or to inhibit the outputs.
