Description and Introduction

8K x 8 Asynchronous CMOS Static RAM The part number HM1-65642B/883 is a military-grade hybrid microcircuit manufactured by Texas Instruments. It is designed to meet MIL-PRF-38534 standards, ensuring high reliability for military and aerospace applications. 

Key specifications include:
- **Manufacturer**: Texas Instruments
- **Part Type**: Hybrid Microcircuit
- **Military Standard**: MIL-PRF-38534
- **Quality Level**: 883 (high-reliability screening)
- **Operating Temperature Range**: Typically -55°C to +125°C (exact range may vary based on datasheet)
- **Package Type**: Hermetically sealed (exact package details depend on variant)
- **Function**: Specific functionality (e.g., amplifier, converter, etc.) would be detailed in the datasheet. 

For precise electrical characteristics, pinout, and application details, consult the official datasheet or Texas Instruments' documentation.

Application Scenarios & Design Considerations

8K x 8 Asynchronous CMOS Static RAM

Alternative Part Number

  • IDT7164S55DB --: 8K x 8 static RAM with similar 55 ns access time and pin-compatible DIP package, suitable as a functional replacement for the HM1-65642B/883.
  • CY7C185-55PC --: 8K x 8 asynchronous SRAM with comparable speed and organization, widely available and commonly used as a cross-reference for 65642-type devices.
  • AS7C164-55PC --: 8K x 8 low-power CMOS SRAM with 55 ns access time, offered as a drop-in replacement for legacy 8K x 8 SRAM parts.
  • IDT7164S85DB --: 8K x 8 static RAM with similar 5V asynchronous architecture and 883-style screening available; widely used as a drop-in replacement for HM1-65642 series in military and industrial designs.
  • CY7C185-35PC --: 8K x 8 high-speed CMOS SRAM with compatible pinout and timing, commonly cross-referenced for Intersil HM1-65642 sockets in legacy systems.
  • AS7C164-15PC --: 8K x 8 low-power CMOS SRAM offering equivalent organization and 5V interface, suitable as a functional substitute when the original military-grade part is unavailable.
