A1458 Optocoupler Datasheet Exclusive [HOT • 2024]
A good A1458 datasheet will show three standard applications:
This section clarifies the specific part numbers and their package variants, such as (PDIP-8) or HCPL-1458-500E (SOIC-8W). The "000E" suffix often denotes the PDIP package with lead-free (RoHS) compliance, while "500E" indicates the SOIC-8W surface-mount package.
Understanding the pinout is crucial for proper circuit integration. While the pinout can vary slightly based on the specific variant (PDIP-8 vs. SOIC-8), the A1458 family generally follows a standard configuration. a1458 optocoupler datasheet
Understanding the electrical and environmental characteristics is critical for proper selection and circuit design. The table below consolidates the core parameters for the A1458 family.
The (often referred to as A1458 ) is a high-speed, single-channel logic gate optocoupler manufactured by Broadcom (formerly Avago). It is designed to bridge the gap between high-speed digital circuits while providing excellent electrical isolation. ⚡ Key Specifications A good A1458 datasheet will show three standard
When a forward current (IF) is applied to the input LED (Anode to Cathode), it emits infrared light. This light crosses the isolation barrier and strikes the photodetector, which activates the output transistor, pulling the output voltage (VO) low. When the input current stops, the output transistor turns off, and the output is pulled high via an external pull-up resistor.
For SMD versions, the profile may be as low as 2.0 mm, suitable for compact designs. While the pinout can vary slightly based on

While a full internal block diagram should be consulted from the official datasheet, the general pin functions are consistent across these packages.
(Note: Always double-check the specific manufacturer’s datasheet, as pin numbering can occasionally differ in SMD versions).
