Questions buyers ask
- Can CD4043 replace CD4043B?
- CD4043 is I-CORE's functional equivalent of CD4043B, HEF4043B in the same DIP-16 / SOP-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 CD4043?
- Supply: 3–15 V. Operating temperature: −40 to 125 °C. See the datasheet for full electrical characteristics.
- Is CD4043 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 CD4043-AX-LJ-D060EN (revision 2023-04-B1). The full datasheet PDF is linked above.
General description
The CD4043 is a quad R/S latch with 3-state outputs with a common output enable input (OE). Each latch has an active HIGH set input (1S to 4S), an active HIGH reset input (1R to 4R) and an active HIGH 3-state output (1Q to 4Q). When OE is HIGH, the latch output (nQ) is determined by the nR and nS inputs as shown in function table. When OE is LOW, the latch outputs are in the high impedance OFF-state. OE does not affect the state of the latch. The high impedance off-state feature allows common bussing of the outputs. It operates over a recommended VDD power supply range of 3V to 15V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.
Key features
- 5V, 10V, and 15V parametric ratings
