74ABT244CPC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT244CPC is an octal buffer and line driver featuring three-state outputs, housed in a 20-lead Plastic Dual-In-Line Package (PDIP). It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of -40°C to +85°C. The device provides non-inverting buffering with guaranteed output skew and simultaneous switching specifications. It includes high-impedance glitch-free bus loading during power cycles and offers nondestructive hot-insertion capability.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Non-inverting octal buffer design with three-state outputs controlled by active-low enable inputs
• High drive strength with 64 mA sink and 32 mA source capabilities for direct load driving
• Glitch-free high-impedance bus loading throughout the entire power-up and power-down cycle
• Nondestructive hot-insertion capability with disable time less than enable time to prevent bus contention

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitter/receiver circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify package type N20A corresponds to the 20-lead PDIP configuration. Confirm supply voltage requirements align with the +4.5V to +5.5V operating range. Check thermal management needs against the -40°C to +85°C ambient temperature rating. Ensure input signal edge rates meet the minimum 50 mV/ns data input requirement. Validate that system logic levels are compatible with the specified VIH and VIL thresholds.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed octal buffering with significant current drive capabilities. It is suitable for applications needing guaranteed output skew and simultaneous switching performance under varying load conditions. Consider its compatibility with standard 5V logic families and its ability to handle hot-insertion scenarios without damage. Evaluate the trade-off between its ABT technology speed and power consumption relative to other buffer families.
