XD74LS247 DIP16, XD74LS248 DIP16

PublishTime：2021-05-19

74LS247, and 74LS248 compose the 5 and with tails. Composition of all other characters, including display patterns for BCD inputs above nine. Is Identical. 74LS247 feature active-low outputs designed for driving Indicators directly, and the 74LS248 features active-high outputs for driving lamp buffers. All of the circuits have full rippie^blanking input/output controls and a lamp test input Segment identification and resultant displays are shown below. Display patterns for BCD input counts above 9 are unique symbols to authenticate input conditions. AII of these circuits incorporate automatic leading and/or traiiing*edae zero-blanking control (RBI and RBO). Lamp test (CT) of these types may be performed at any time when the bF/RBO node Is at a high level. AH types contain an overriding blanking input (BO which can be used to control tile lamp intensity by pulsing or to inhibit the outputs. Inputs and outputs are entirely compatible for use with TTL logic outputs. Series 74 and Series 74LS devices are characterized for operation from 0°C to 70°C.
