From Makers Electronics's description

7442 BCD to Decimal Decoder 5V 28mA IC DIP-16 The 7442 BCD-to-Decimal Decoder is a combinational logic integrated circuit designed to decode Binary-Coded Decimal (BCD) inputs into corresponding decimal output lines. It accepts four input bits and activates one of ten output lines representing decimal digits 0 through 9, simplifying the implementation of decimal selection and control circuits. The IC uses active-low outputs, meaning the selected output goes LOW while the other valid decimal outputs remain HIGH. Its DIP-16 through-hole package is suitable for printed circuit boards, digital electronics projects, and educational experiments. The 7442 is a decoder rather than a BCD-to-seven-segment driver, so additional circuitry may be needed when connecting it to a seven-segment display. Features: Single 7-Segment to BCD Decoder. Outputs Directly Interface to CMOS, NMOS and TTL. Large Operating Voltage Range. Wide Operating Conditions. Specifications: Product Attribute Attribute Value Product: Decoders / Demultiplexers Number of Input Lines: 4 Input Number of Output Lines: 10 Output Propagation Delay Time: 30 ns Supply Voltage – Min: 4.75 V Supply Voltage – Max: 5.25 V Minimum Operating Temperature: 0 C Maximum Operating Temperature: + 70 C Mounting Style: Through Hole Package/Case: PDIP-16 Packaging: Tube Function: 4 to 10 BCD Height: 4.57 mm High Level Output Current: – 0.4 mA Input Voltage: 2.0 V to 0.8 V Length: 19.3 mm Logic Type: Decoder Low Level Output Current: 8 mA Maximum Clock Frequency: 35 MHz Number of Circuits: Dual Operating Supply Voltage: 5 V Operating Temperature Range: 0 C to + 70 C Output Current: 8 mA Output Voltage: + 0.4 V to + 0.5 V Subcategory: Logic ICs Supply Current – Max: 7 mA Pinout: Applications: BCD decoding circuits.
