Questions buyers ask
- Can AiP74HC42 replace SN74HC42?
- AiP74HC42 is I-CORE's functional equivalent of SN74HC42, 74HC42 in the same SOP-16 package. Standard parts in this family share the industry pinout, but please compare both datasheets — supply range, timing and absolute maximum ratings — before design-in.
- What is the supply voltage and temperature range of AiP74HC42?
- Supply: 2.0–6.0 V. Operating temperature: −40 to 125 °C. See the datasheet for full electrical characteristics.
- Is AiP74HC42 in stock, and can I get a free sample?
- Yes, it is held in stock in Shenzhen. Free samples are available for evaluation, with shipping paid by us. For production orders, SMD parts can be ordered from 1 pc and DIP parts ship in full tubes; orders ship within 2–3 business days after payment.
- Is it original I-CORE product?
- Yes. We supply factory-original I-CORE (Wuxi I-CORE Electronics) parts in sealed reels and tubes. Our ISO 9001, ISO 14001 and ISO 45001 certificates are shown on the home page; RoHS and REACH test reports are available on request.
Datasheet highlights
From the I-CORE English datasheet AiP74HC/HCT42-AX-LJ-A037EN (revision 2023-04-B1). The full datasheet PDF is linked above.
General description
The AiP74HC/HCT42 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.
