Nexperia HEF4049BT Hex Inverting Buffer, SOIC-16

The Nexperia HEF4049BT is a high-performance hex inverting buffer designed for demanding industrial and automation applications. With its high-current output capability, this IC is ideal for driving TTL logic or high-capacitive loads, ensuring reliable signal transmission in complex electronic systems.

This buffer accepts input voltages exceeding its own supply voltage, allowing logic level conversion from up to 15V down to standard TTL levels. The device operates over a wide supply range from 3V to 15V, with recommended parametric ratings at 5V, 10V, and 15V, and fully static operation for stable performance across all conditions.

The HEF4049BT features standardized symmetrical output characteristics and complies with the JEDEC standard JESD 13-B, ensuring compatibility with industry norms. Packaged in a compact SOIC-16 case, this component is suitable for space-constrained PCB layouts.

Unused inputs must be connected to VDD, VSS, or another input to ensure proper functionality. With an operating temperature range of -40°C to +85°C, this buffer is robust enough for harsh environments.
