Overview
The NATIONAL SEMICONDUCTOR 74HC244 is a high-performance, octal noninverting buffer designed for bus-oriented systems, offering direct interface capabilities with CMOS, NMOS, and TTL logic families. Its primary function is to provide robust signal buffering and line driving, crucial for managing multiple data lines in complex digital architectures. A key design consideration is managing the inherent propagation delay introduced by the CMOS switching characteristics, especially when operating at the higher end of its 2.0 to 6.0 V supply range, which can impact timing-critical applications. This device is pin-compatible with LS244, facilitating seamless upgrades in existing designs.
Key Features
- Octal Noninverting Buffer/Line Driver
- 3-State Outputs with Active-Low Enables
- Output Drive Capability: 15 LSTTL Loads
- Wide Operating Voltage Range: 2.0 V to 6.0 V
- Low Input Current: 1.0 µA
- Dimensions: Standard 20-pin PDIP/SOIC packages
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- High-speed memory address buffering
