The HEF4543BT,652 from Nexperia is a versatile BCD to 7-segment latch/decoder/driver IC. It is suitable for driving both liquid crystal and LED displays, offering a flexible solution for various display applications.
This device features a wide operating supply voltage range from 3 V to 15 V, making it adaptable to different system requirements. It operates reliably within a temperature range of -40 °C to +85 °C. The HEF4543BT,652 includes a 4-bit storage latch and an 8-4-2-1 BCD to 7-segment decoder/driver.
Key inputs include address inputs (D0-D3), an active LOW latch enable (LE), an active HIGH blanking input (BL), and an active HIGH phase input (PH). The seven buffered segment outputs (Qa-Qg) are designed to drive display segments directly. For liquid crystal displays, a square-wave is applied to the PH input and the display's back-plane.
The HEF4543BT,652 is supplied in a 16-lead SOIC package with a body width of 3.9 mm, suitable for surface mounting. It offers CMOS low power dissipation and high noise immunity, ensuring robust performance in demanding environments.
