Questions buyers ask
- Can AiP74HCT244 replace SN74HCT244?
- AiP74HCT244 is I-CORE's functional equivalent of SN74HCT244, 74HCT244 in the same SOP-20 / TSSOP-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.
- How is AiP74HCT244 different from AiP74HC244?
- Both are covered by the same I-CORE datasheet. AiP74HCT244 has TTL-compatible inputs (VIH min. 2.0 V) and runs from 4.5–5.5 V, so it can be driven directly by TTL-level or 3.3 V logic in a 5 V system. AiP74HC244 has CMOS input thresholds and runs from 2.0–6.0 V.
- What is the supply voltage and temperature range of AiP74HCT244?
- Supply: 4.5–5.5 V. Operating temperature: −40 to 125 °C. See the datasheet for full electrical characteristics.
- Is AiP74HCT244 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/HCT244-AX-LJ-A020EN (revision 2023-04-B1). The full datasheet PDF is linked above.
General description
The AiP74HC/HCT244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two — 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
