Questions buyers ask
- Can AiP74HCT573 replace SN74HCT573?
- AiP74HCT573 is I-CORE's functional equivalent of SN74HCT573, 74HCT573 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 AiP74HCT573 different from AiP74HC573TA20.TR?
- Both are covered by the same I-CORE datasheet. AiP74HCT573 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. AiP74HC573TA20.TR has CMOS input thresholds and runs from 2.0–6.0 V.
- What is the supply voltage and temperature range of AiP74HCT573?
- Supply: 4.5–5.5 V. Operating temperature: −40 to 125 °C. See the datasheet for full electrical characteristics.
- Is AiP74HCT573 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/HCT573-AX-LJ-A024EN (revision 2023-04-B1). The full datasheet PDF is linked above.
General description
The AiP74HC/HCT573 is an 8-bit D-type transparent latch with 3-state outputs. The device features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs enter the latches. In this condition the latches are transparent, a latch output will change each time its corresponding D-input changes. When LE is LOW the latches store the information that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the latches. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
