Questions buyers ask
- Can AiP74HC540 replace SN74HC540?
- AiP74HC540 is I-CORE's functional equivalent of SN74HC540, 74HC540 in the same DIP-20 / SOP-20 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 AiP74HC540?
- Supply: 2.0–6.0 V. Operating temperature: −40 to 125 °C. See the datasheet for full electrical characteristics.
- Is AiP74HC540 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/HCT540-AX-LJ-A028EN (revision 2023-04-B1). The full datasheet PDF is linked above.
General description
The AiP74HC/HCT540 is an 8-bit inverting buffer/line driver with 3-state outputs. The device features — two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
