The Nexperia HEF4794BT is an 8-stage serial shift register designed for LED driver applications. Each stage includes a storage latch, allowing data to be strobed from a serial input (D) to parallel outputs (QP0 to QP7). Data shifts on positive-going clock transitions (CP), and is transferred to the storage register when the strobe input (STR) is HIGH. The outputs are enabled when the output enable input (OE) is HIGH.
This device features two serial outputs, QS1 and QS2, for cascading multiple HEF4794B units. QS1 provides serial data on positive-going clock edges for high-speed operation, while QS2 offers the same data on the subsequent negative-going clock edge, suitable for slower clock rise times. The HEF4794BT operates with a recommended supply voltage (VDD) range of 3V to 15V referenced to VSS (ground).
It is specified for operation across a wide temperature range, from -40°C to +125°C, making it suitable for demanding industrial environments. The HEF4794BT comes in a 16-lead SOIC (SO16) surface-mount package. Unused inputs should be connected to VDD, VSS, or another input to ensure proper operation.
