NTE74LS47 Datasheet | NTE Electronics

Description : The NTE74LS47 is a BCD- to- Seven- Segment Decoder/Driver in a 16- Lead plastic DIP type package that features active- low outputs designed for driving mon- anode VLEDs or incandescent indicators directly. This device has full ripple- blanking input/output controls and a lamp test input. Display patterns for BCD input count above 9 are unique symbols to authenticate input conditions. The NTE74LS47 incorporates automatic leading and/or trailing- edge zero- blanking control (RBI and RBO). Lamp test (LT) may be performed at any time when the BI/RBO node is set at a high level. This device also contains an overriding blanking input (BI) which can be used to control the lamp intensity by pulsing or to inhibit the outputs. Inputs and outputs are entirely patible for use with TTL logic outputs.
