MC74LVX244DTR2G

Overview

The MC74LVX244DTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the 74LVX logic series. It features eight non-inverting channels with three-state outputs, housed in a 20-TSSOP surface-mount package. The device operates within a supply voltage range of 2 V to 3.6 V. Key electrical parameters include a maximum static current of 4 uA and a power dissipation of 180 mW. Propagation delays are specified at 14.9 ns at 2.7 V and 10.6 ns at 3.3 V. Output drive capabilities provide 4 mA for both high and low states. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides eight non-inverting signal paths with independent three-state control for bus-oriented communication.
• Operates effectively across a wide low-voltage supply range from 2 V to 3.6 V.
• Features ultra-low static power consumption suitable for battery-powered applications.

Applications

• Memory mapping controls
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix DTR2G to confirm the tape-and-reel packaging format and lead-free status. Ensure the order matches the 20-TSSOP footprint requirements. Confirm RoHS compliance details via the manufacturer's official documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state isolation at low voltages. It serves as a direct replacement for standard 74FCT244 devices in 3.3 V environments. Consider the 10.6 ns propagation delay at 3.3 V for timing-critical bus applications.

Part Context

This part belongs to the 74LVX family, which combines CMOS performance with TTL-compatible inputs. It is designed for low-voltage digital systems. The TSSOP-20 package offers a compact solution for space-constrained printed circuit board layouts while maintaining robust signal integrity.

Replacement Considerations

SN74LV244APWR is a confirmed direct substitute from Texas Instruments.
