The CD74FCT244ATQM is a dual-channel, non-inverting buffer from Harris Corporation's 74FCT family. It operates from a 4.75V to 5.25V supply, delivering 15mA source and 64mA sink current. With 3-State outputs, it is ideal for bus-oriented applications. Housed in a 20-SSOP package, this buffer is designed for 5V digital systems requiring signal buffering and fan-out, with a commercial temperature range of 0°C to 70°C.
- Dual Channels: Buffers two independent signals in one package, saving board space.
- High Sink Current (64mA): Provides strong drive for capacitive loads and long traces.
- 3-State Outputs: Enables bus sharing and reduces power consumption when idle.
- Compact SSOP Package: Ideal for space-constrained designs.
5V Bus Buffering
Use the CD74FCT244ATQM to buffer address or control lines in 5V systems. The 2 channels allow buffering of two independent signals, while 3-State outputs enable bus sharing.
Signal Fan-Out
Drive multiple loads from a single source. The buffer's 64mA sink current ensures each load receives a clean, strong signal without degradation.
Memory Address Buffering
Buffer address lines to SRAM or DRAM in embedded systems. The non-inverting function preserves address polarity, simplifying design.
Peripheral Control Signal Driver
Drive chip-select or enable signals to multiple peripherals. The 3-State outputs allow easy disabling of unused peripherals to save power.
Industrial Control Logic
In factory automation, buffer sensor or actuator control signals. The 0°C to 70°C range covers most indoor industrial environments.
Test and Measurement Equipment
Buffer trigger signals or data lines in benchtop instruments. The high drive current ensures accurate signal transmission over short distances.
