SNJ54BCT244W

Overview

The SNJ54BCT244W is an octal buffer and line driver utilizing state-of-the-art BiCMOS technology. It features two independent 4-bit buffers with separate active-low output-enable inputs. The device provides non-inverting data transfer from A inputs to Y outputs when enabled, entering a high-impedance state otherwise. Designed for military applications, it operates over the full temperature range of -55°C to 125°C with a supply voltage of 4.5V to 5.5V. It offers low quiescent current and ESD protection exceeding 2000V per MIL-STD-883C.

Feature Summary

• State-of-the-art BiCMOS design significantly reduces quiescent current
• P-N-P inputs reduce DC loading on driving circuits
• ESD protection exceeds 2000 V per MIL-STD-883C Method 3015
• 3-state outputs suitable for bus lines or memory address registers

Applications

• 3-state memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters
