Questions buyers ask
- Can AiP74HC390 replace SN74HC390?
- AiP74HC390 is I-CORE's functional equivalent of SN74HC390, 74HC390 in the same SOP-16 / DIP-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 AiP74HC390?
- Supply: 2.0–6.0 V. Operating temperature: −40 to 125 °C. See the datasheet for full electrical characteristics.
- Is AiP74HC390 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/HCT390-AX-LJ-A089EN (revision 2022-08-A1). The full datasheet PDF is linked above.
General description
The AiP74HC/HCT390 is a dual 4-bit decade ripple counter divided into four separately clocked sections. The counters have two divide-by-2 sections and two divide-by-5 sections. These sections share an asynchronous master reset input (nMR) and can be used in a BCD decade or bi-quinary configuration. If master reset inputs 1MR and 2MR are used to clear all 8 bits of the counter simultaneously, numerous counting configurations are possible within one package. Section clocks n CP 0 and n CP 1 , allow ripple counter or frequency division applications of divide-by-2, 4, 5, 10, 20, 25, 50 or 100. The HIGH-to-LOW transition of the clock inputs n CP 0 and n CP 1 trigger each section. For BCD decade operation, the nQ0 output is connected to the n CP 1 input of the divide-by-5 section.
