Questions buyers ask
- Can AiP74HC139 replace SN74HC139?
- AiP74HC139 is I-CORE's functional equivalent of SN74HC139, 74HC139 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.
- Is there a TTL-input version of AiP74HC139?
- Yes. AiP74HCT139 is the HCT version from the same I-CORE datasheet: TTL-compatible inputs (VIH min. 2.0 V), 4.5–5.5 V supply. AiP74HC139 has CMOS input thresholds and runs from 2.0–6.0 V.
- What is the supply voltage and temperature range of AiP74HC139?
- Supply: 2.0–6.0 V. Operating temperature: −40 to 125 °C. See the datasheet for full electrical characteristics.
- Is AiP74HC139 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/HCT139-AX-LJ-A044EN (revision 2023-04-B1). The full datasheet PDF is linked above.
General description
The AiP74HC/HCT139 decodes two binary weighted address inputs (nA0, nA1) to four mutually — — exclusive outputs (nY0 to nY3). Each decoder features an enable input (nE). When nE is HIGH all outputs are forced HIGH. The enable input can be used as the data input for a 1-to-4 demultiplexer application. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
