Overview
BCD TO 7-SEGMENT DECODER/DRIVER The SN54 / 74LS47 are Low Power Schottky BCD to 7-Segment Decoder / Drivers consisting of NAND gates, input buffers and seven AND-OR-INVERT gates.
They offer active LOW, high sink current outputs for driving indicators directly.
Seven NAND gates and one driver are connected in pairs to make BCD data and its complement available to the seven decoding AND-OR-INVERT gates.
The remaining NAND gate and three input buffers provide lamp test, blanking input / ripple-blanking output and ripple-blanking input.
The circuits accept 4-bit binary-coded-decimal (BCD) and, depending on the state of the auxiliary inputs, decodes 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 SN54 / 74LS47 are designed to withstand the relatively high voltages required for 7-segment indicators.
These outputs will withstand 15 V ...
