MC74LVX244DTR2

Overview

The MC74LVX244DTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the LVX logic series. It features eight non-inverting channels with three-state outputs housed in a TSSOP-20 package. The device operates within a supply voltage range of 2 V to 3.6 V. Key electrical parameters include a maximum high-level output current of -4 mA and a low-level output current of 4 mA. Static current is specified at 4 uA, while operating power consumption reaches 40 uA. Propagation delay varies from 14.9 ns at 2.7 V to 10.6 ns at 3.3 V. Power dissipation is rated at 180 mW, and the component supports surface mount installation across a temperature range of -40°C to +85°C.

Feature Summary

• Provides eight non-inverting signal paths for buffering or driving applications
• Features three-state outputs to facilitate bus-oriented architectures
• Operates efficiently within a low-voltage range of 2 V to 3.6 V
• Delivers moderate drive capability suitable for standard digital loads

Applications

• Bus-oriented memory and signal switching systems
• Clock drivers and buffer circuits
• Mobile and handheld equipment requiring low voltage operation

Procurement Notes

Verify the complete part number includes the trailing 'G' suffix (MC74LVX244DTR2G) to confirm RoHS compliance and lead-free status as per manufacturer specifications. Confirm the package type matches the required TSSOP-20 footprint for PCB layout compatibility. Ensure the voltage domain of the target application aligns with the 2 V to 3.6 V operational limits to prevent device malfunction.

Selection Notes

Select this component when designing systems that require octal buffering with tri-state control under low-voltage conditions. It serves as a direct replacement for other LVX-series buffers in similar packages. Consider the propagation delay characteristics relative to system clock speeds. Verify that the 4 mA output drive strength meets the capacitive load requirements of the connected circuitry without exceeding power dissipation limits.
