Product Description

The SN74LS47N is a BCD-to-Seven-segment Decoder/Driver features active-low outputs, designed for driving, common-anode LEDs or incandescent indicators directly. The IC for driving lamp buffers or common-cathode LEDs. All of the circuits except LS49 have full ripple-blanking input/output controls and a lamp test input. Display patterns for BCD input counts above 9 are unique symbols to authenticate input conditions. Its circuits incorporate automatic leading and/or trailing-edge zero-blanking control (RBI\ and RBO\\). Lamp test (LT/) of these types may be performed at any time when the BI\/RBO\ node is at a high level. All types (including the "49 and "LS49) contain 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 compatible for use with TTL logic outputs.
