HEF4794BT Description

Short technical summary and product information.

The HEF4794B is an 8-stage serial shift register from NXP Semiconductors, designed for LED driver applications. It features a storage latch for each stage, enabling data to be strobed from a serial input (D) to parallel LED driver outputs (QP0 to QP7). Data shifts on positive-going clock (CP) transitions.

 

This device operates over a recommended VDD power supply range of 3 V to 15 V. It is specified for operation across a wide temperature range, from -40 °C to +125 °C. The HEF4794BT comes in a 16-lead SOIC (SO16) plastic small outline package, suitable for surface mount applications.

 

Key features include fully static operation, standardized symmetrical output characteristics, and the availability of two serial outputs (QS1 and QS2) for cascading multiple devices. Unused inputs should be connected to VDD, VSS, or another input to ensure proper operation.
