The 74VHCT244AMTCX is a high-speed CMOS octal buffer with 3-State outputs, optimized for 5V systems. Operating from 4.5V to 5.5V, it delivers 8mA output current per channel. TTL-compatible inputs allow interfacing with 3.3V logic. The non-inverting buffer preserves signal integrity, and 3-State outputs enable bus sharing. Packaged in 20-TSSOP, it is ideal for memory interfacing, industrial controls, and telecom applications.
- TTL-Compatible Inputs: Directly interface with 3.3V logic without level shifters.
- High Output Current (8mA): Drives LEDs, relays, and capacitive loads effectively.
- 3-State Outputs: Facilitate bus multiplexing and hot-swap designs.
- Very High-Speed CMOS: Low propagation delay for high-frequency applications.
5V Bus Interfacing
Buffer address/data buses in 5V microcontroller systems. The TTL-compatible inputs allow direct connection to 3.3V logic without level shifters, simplifying mixed-voltage designs.
Memory Expansion
Drive multiple memory banks with 3-State outputs. The 8mA output current handles capacitive loads of SRAM or EEPROM, ensuring reliable read/write operations.
Peripheral Driver
Drive LEDs, relays, or optocouplers with the 8mA output capability. The non-inverting buffer maintains signal polarity for straightforward control logic.
Industrial Control Panels
Buffer signals from PLCs to field devices. The -40°C to 85°C range covers most industrial environments, and 3-State outputs prevent bus contention.
Test Equipment
Use in signal routing for automated test setups. The high-speed VHCT technology provides fast switching, essential for accurate timing measurements.
Telecom Line Cards
Buffer control signals in telecom equipment. The 5V operation matches legacy telecom logic, while 3-State outputs enable hot-swap capabilities.
