Questions buyers ask
- Can AiP74HC161 replace SN74HC161?
- AiP74HC161 is I-CORE's functional equivalent of SN74HC161, 74HC161 in the same SOP-16 / TSSOP-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.
- What is the supply voltage and temperature range of AiP74HC161?
- Supply: 2.0–6.0 V. Operating temperature: −40 to 125 °C. See the datasheet for full electrical characteristics.
- Is AiP74HC161 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/HCT161-AX-LJ-A060EN (revision 2023-04-B1). The full datasheet PDF is linked above.
General description
The AiP74HC/HCT161 is a synchronous presettable binary counter with an internal look-head carry. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock (CP). The outputs (Q0 to Q3) of the counters may be preset HIGH or LOW. A LOW at the parallel enable input (PE) disables the counting action and causes the data at the data inputs (D0 to D3) to be loaded into the counter on the positive-going edge of the clock. Preset takes place regardless of the levels at count enable inputs (CEP and CET). A LOW at the master reset input (MR) sets Q0 to Q3 LOW regardless of the levels at input pins CP, PE, CET and CEP (thus providing an asynchronous clear or function). The look-ahead carry simplifies serial cascading of the counters. Both CEP and CET must be HIGH to count.
