HDSP-2534

HDSP-2534 is a four-digit, seven-segment LED display module from Hewlett-Packard’s HDSP family. It’s used for numeric readouts in older instrumentation, typically showing red digits (with optional decimal points). The digits are multiplexed: a common set of segment lines is shared across digits, while four digit-select lines enable one digit at a time. It usually runs at 5V and requires external current limiting (resistors or a constant-current driver) and a driver or microcontroller to control the segments and digit enables. The pin count is in the 14–16 pin range, providing segment lines and digit selectors. Today it’s largely a legacy/surplus part, originally used in HP/Agilent instruments; for new designs, people often use more common LED display modules or dedicated LED drivers.

HDSP-2534 isn’t a unique part number by itself—different vendors use similar codes for different devices. To give exact equivalents I need the device function and manufacturer (or the datasheet). Please specify what HDSP-2534 is (e.g., LED driver, op-amp, ADC/DAC, optocoupler) and share the datasheet. I’ll then provide cross‑references from TI, Analog Devices, ST, NXP, etc., with matching pinouts and specs.

HDSP-2534 packaging isn’t fixed; different vendors use it for different devices. LED display modules and photodiode assemblies can have different housings (DIP, SOP/SO-16, etc.). Please specify the manufacturer or share the datasheet to identify the exact package.
