Display Drivers datasheet and documents for MM5450YN
Display Drivers Overview
The MM5450YN is a monolithic LED display driver manufactured by Microchip Technology, housed in a 40-pin PDIP package. It supports up to 3.5-digit displays with 7-segment output capability. The device operates on a supply voltage range of 4.75V to 11V and draws a maximum supply current of 10mA. It features serial data input for microprocessor interfacing and provides TTL-compatible logic levels. The operating temperature range extends from -40°C to +85°C, suitable for industrial applications.
Display Drivers Feature Summary
- Continuous brightness control via a single external resistor connected to the reference pin
- Serial data input interface compatible with most microprocessors without requiring additional load signals
- Wide power supply operation range supporting both low-voltage and standard logic systems
Display Drivers Applications
- Industrial control system displays
- Digital clock readouts
- Thermometer instrumentation
- Voltage meter displays
Display Drivers Procurement Notes
Verify component authenticity through authorized Microchip distributors or official manufacturer channels. Confirm the specific suffix 'YN' corresponds to the 40-PDIP package variant. Check for obsolescence status as some variants in this series may be discontinued. Ensure environmental compliance documentation matches project requirements.
Display Drivers Selection Notes
Select the MM5450YN when a through-hole 40-pin DIP package is required for legacy board designs. Choose this model over surface-mount variants if manual assembly or prototyping flexibility is needed. Ensure the application requires only 7-segment output rather than the alphanumeric capability found in the MM5451 series.
Display Drivers Part Context
This component belongs to the MM5450/5451 family of LED display drivers. These integrated circuits utilize N-channel metal-gate MOS technology to combine enhancement-mode and depletion-mode device advantages. The family is designed for driving common-anode LED displays with minimal external components.
