Questions buyers ask
- Can AiP74HCT164 replace SN74HCT164?
- AiP74HCT164 is I-CORE's functional equivalent of SN74HCT164, 74HCT164 in the same TSSOP-14 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 AiP74HCT164 different from AIP74HC164SA14.TR?
- Both are covered by the same I-CORE datasheet. AiP74HCT164 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. AIP74HC164SA14.TR has CMOS input thresholds and runs from 2.0–6.0 V.
- What is the supply voltage and temperature range of AiP74HCT164?
- Supply: 4.5–5.5 V. Operating temperature: −40 to 125 °C. See the datasheet for full electrical characteristics.
- Is AiP74HCT164 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/HCT164-AX-LJ-A015EN (revision 2026-05-B2). The full datasheet PDF is linked above.
General description
The AiP74HC/HCT164 is an 8-bit serial-in/parallel-out shift register. The device features two serial data inputs (DSA and DSB), eight parallel data outputs (Q0 to Q7). Data is entered serially through DSA or DSB and either input can be used as an active HIGH enable for data entry through the other input. Data is shifted on the LOW-to-HIGH transitions of the clock (CP) input. A LOW on the master reset input (MR) clears the register and forces all outputs LOW, independently of other inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
