HEF4021BT,653 Description

Short technical summary and product information.

The HEF4021BT,653 from Nexperia is an 8-bit static shift register, functioning as a parallel-to-serial converter. It features a wide operating supply voltage range from 3.0 V to 15.0 V, making it versatile for different power requirements. The device operates reliably within a temperature range of -40 °C to +125 °C.

 

This shift register supports both parallel and serial data input, with a synchronous serial data input (DS) and asynchronous parallel data inputs (D0 to D7). It includes buffered parallel outputs from the last three stages (Q5 to Q7). The clock input (CP) benefits from Schmitt trigger action, providing tolerance to slower rise and fall times. The HEF4021BT,653 is housed in a 16-SOIC package, designed for surface mount applications.

 

Key electrical characteristics include its 3V to 15V voltage capability and push-pull output type. With 8 bits per element and a single element, it is well-suited for applications requiring data serialization or temporary storage. The device's static operation ensures reliable performance under various conditions.
