The MC74LCX244DWR2G is a dual 4-bit non-inverting buffer from onsemi, designed for low-voltage applications. Operating from 2V to 5.5V, it features 5V tolerant inputs, allowing direct interfacing with higher-voltage logic. The 3-State outputs and 24mA drive capability make it suitable for bus-oriented systems. The 74LCX family offers high speed with low power consumption, ideal for battery-powered devices. Housed in a 20-SOIC package, this buffer operates over -55°C to 125°C, supporting automotive and industrial applications. Its dual-channel design with independent enables provides flexible control in complex systems.
- 5V Tolerant Inputs: Allows direct connection to 5V logic without level shifting, simplifying design.
- Wide 2V to 5.5V Supply: Compatible with 2.5V, 3.3V, and 5V systems, offering design flexibility.
- 24mA Output Drive: Drives capacitive loads effectively, maintaining signal integrity.
- Dual-Channel with Independent Enables: Provides granular control for complex bus architectures.
- Extended Temperature Range: -55°C to 125°C suitable for harsh environments.
5V Tolerant Input Interfacing
The MC74LCX244DWR2G features 5V tolerant inputs even when powered at 2V, allowing direct connection to 5V logic without damage. This simplifies mixed-voltage system design.
Memory Address Buffering
Use this buffer to drive address lines in memory systems. The 24mA output drive ensures fast charging of parasitic capacitance, reducing access times in SRAM/DRAM designs.
Peripheral Bus Isolation
The 3-State outputs with separate enable pins allow individual isolation of peripheral devices from the main bus, useful in hot-swap or power-management applications.
Level Shifting for 3.3V to 5V Systems
When powered at 3.3V, the 5V tolerant inputs accept 5V signals, while outputs drive 3.3V logic. This provides a simple unidirectional level-shifting solution.
Industrial Sensor Buffering
In industrial control, this buffer conditions signals from sensors and encoders, providing clean digital outputs to PLCs. The -55°C to 125°C range covers extreme environments.
Telecommunications Equipment
In telecom line cards, the low-voltage operation and high-speed performance make this buffer suitable for interfacing DSPs with line drivers and receivers.
