The CD74FCT162244ETMT is a high-performance, non-inverting buffer from Harris Corporation, designed for 5V logic systems. It provides 4 channels of signal buffering with 3-State outputs, enabling bus isolation and load driving. Operating from 4.5V to 5.5V, it delivers 24mA of output current, making it ideal for driving LEDs, bus lines, and multiple logic inputs. This buffer is well-suited for microcontroller interfacing, clock distribution, and industrial control applications.
- 4-Channel Buffering: Provides multiple independent buffers in a single package, saving board space and cost.
- 3-State Outputs: Enables bus sharing and output isolation, increasing system flexibility.
- 24mA Output Drive: Capable of driving high-capacitance loads and multiple inputs directly.
- 74FCT High-Speed Logic: Ensures minimal propagation delay, critical for timing-sensitive applications.
Signal Buffering for Microcontrollers
Use the CD74FCT162244ETMT to buffer output signals from a 5V microcontroller. This protects the MCU from excessive load and ensures signals reach their destination with full voltage levels.
Driving Multiple LED Indicators
With 24mA output capability, this buffer can directly drive multiple LEDs. The 3-State outputs allow you to turn off entire banks of LEDs for power saving.
Bus Line Driving in 5V Systems
Drive long bus lines in legacy 5V industrial equipment. The buffer provides the necessary current to overcome line capacitance and maintain signal integrity.
Clock Distribution
Buffer and distribute clock signals to multiple peripherals. The 4 channels allow fan-out to four separate loads with minimal skew.
Memory Address Line Buffering
Buffer address lines from a processor to multiple memory chips. This reduces the load on the processor's address pins and improves timing margins.
Test Equipment Interface
In automated test equipment, use this buffer to drive signals to a device under test (DUT). The 3-State outputs allow the test system to disconnect from the DUT when not in use.
