Overview
The Rochester Electronics 55501EJ/BQA is an AC Plasma Display Driver manufactured using BICMOS technology. It supports a 32-segment display configuration and features serial data input mode. The device is housed in a 40-lead Ceramic Dual In-Line Package (CDIP) with a metal-sealed cofired body. It operates within a supply voltage range of 10.8 V to 13.2 V, with a nominal rating of 12 V. The component is qualified for military-grade reliability, functioning reliably between -55 °C and +125 °C.
Feature Summary
- Supports 32-segment dot matrix display driving capabilities
- Utilizes BICMOS process technology for high performance
- Features serial data input interface for control signals
- Constructed in a hermetically sealed ceramic DIP package
Applications
- Military avionics display systems
- Ruggedized industrial instrumentation panels
- Spacecraft operational control interfaces
Procurement Notes
Verify the specific suffix BQA against official manufacturer documentation to confirm exact testing and screening levels. Ensure the CDIP40 package dimensions match the target footprint. Confirm that the serial input protocol aligns with the system controller requirements before integration into the design.
Selection Notes
Select this component when a hermetically sealed driver for AC plasma displays is required in extreme temperature environments. The BICMOS technology offers a balance of speed and power efficiency suitable for legacy military systems. Verify compatibility with existing 12 V power rails and serial communication buses during the initial design phase.
Part Context
This part belongs to the family of AC plasma display drivers designed for high-reliability applications. Rochester Electronics provides these components to support long-term availability for defense and aerospace platforms where standard commercial sources are discontinued. The ceramic packaging ensures environmental sealing critical for harsh operating conditions.
Replacement Considerations
Direct pin-to-pin replacements may be limited due to the specialized ceramic DIP packaging. Evaluate other BICMOS-based AC plasma drivers from manufacturers offering military-grade equivalents. Verify that any substitute maintains the same 32-segment addressing capability and serial interface timing specifications.
