SEVEN SEGMENT DECODER/DRIVER
The SN74LS47N is a Low Power Schottky BCD to 7-Segment Decoder/Drivers feature active-low outputs, designed for driving, common-anode LEDs or incandescent indicators directly. This article mainly introduces features, pinout, datasheet and other detailed information about Rochester Electronics, LLC SN74LS47N.
SN74LS47N
The SN74LS47N is a Low Power Schottky BCD to 7-Segment Decoder/Drivers feature 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.
The circuits accept 4-bit binary-coded-decimal (BCD) and, depending on the state of the auxiliary inputs, decode this data to drive a 7-segment display indicator. The relative positive-logic output levels, as well as conditions required at the auxiliary inputs, are shown in the truth tables. Output configurations of the SN74LS47N are designed to withstand the relatively high voltages required for 7-segment indicators.
These outputs will withstand 15 V with a maximum reverse current of 250μA. Indicator segments requiring up to 24 mA of current may be driven directly from the SN74LS47N high-performance output transistors. Display patterns for BCD input counts above nine are unique symbols to authenticate input conditions.
