Nexperia B.V. BCD to decimal decoder (1-of-10) 74HC42D,652

The 74HC42 is a one of ten BCD to decimal decoder. It accepts four BCD inputs (0A to 3A) and provides ten mutually exclusive outputs (0Y to 9Y). The logic design ensures that all outputs are HIGH when binary codes greater than nine are applied to the inputs. The most significant input (3A) produces an useful inhibit function when the device is used as a 1-of-8 decoder. The 3A input can also be used as the data input in an 8-output demultiplexer application. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Features and benefits Complies with JEDEC standard no. 7A Wide supply voltage range from 2.0 V to 6.0 V CMOS low power dissipation High noise immunity Input levels: For 74HC42 : CMOS level Mutually exclusive outputs 1-of-8 demultiplexing capability Outputs disabled for input codes above nine Latch-up performance exceeds 100 mA per JESD 78 Class II Level B ESD protection: HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V Specified from -40 °C to +85 °C and -40 °C to +125 °C
