RÖHM BU4S584G2 Logic Inverter IC, Schmitt-Trigger, Single, SSOP-5

The RÖHM BU4S584G2-TR is a general-purpose CMOS logic single Schmitt-trigger inverter gate. This integrated circuit provides a reliable digital logic function, converting a high input to a low output and vice versa, with the added benefit of a Schmitt-trigger input for improved noise immunity and signal conditioning.

A buffer is integrated with the inverter at the gate output, which enhances the input/output transmission characteristics. This design also minimises variations in the propagation delay time that can occur with increases in load capacitance, ensuring consistent and predictable performance in digital circuits.

Key features of this logic IC include exceptionally low power consumption, making it suitable for battery-powered or energy-sensitive applications. It offers high noise immunity, which is critical for maintaining signal integrity in electrically noisy industrial environments. The device supports a wide operating supply voltage range from 3V to 16V, providing significant design flexibility. Its high input impedance minimises loading on preceding circuit stages, while its high fan-out capability allows it to drive multiple inputs downstream. Specifically, the output can directly drive 2 L-TTL inputs or 1 LS-TTL input.

Housed in a compact SSOP (Shrink Small-Outline Package) with 5 pins, this component is designed for space-constrained PCB layouts. Its robust specifications, including an operating temperature range from -40°C to 85°C, make it a versatile choice for demanding applications.
