These monolithic BCD-to-decimal decoder/drivers consist of eight invertersand ten four-input NAND gates. The inverters are connected in pairs to makeBCD input data available for decoding by the NAND gates. Full decoding ofvalid BCD input logic ensures that all outputs remain off for all invalidbinary input conditions. These decoders feature high-performance, n-p-n outputtransistors designed for use as indicator/relay drivers or as open-collectorlogic-circuit drivers. Each of the high-breakdown output transistors (15 volts)of the SN54145, SN74145, or SN74LS145 will sink up to 80 milliamperes of current.Each input is one Series 54/74 or Series 54LS/74LS standard load, respectively.Inputs and outputs are entirely compatible for use with TTL or DTL logic circuits,and the outputs are compatible for interfacing with most MOS integrated circuits.Power dissipation is typically 215 milliwatts for the '145 and 35 milliwattsfor the 'LS145.
