The TC74ACT244FT(EL.PP) is a high-speed octal buffer/line driver with three-state outputs from Toshiba Semiconductor and Storage, belonging to the Advanced CMOS Technology (ACT) logic family. This device operates with a supply voltage of 4.5V to 5.5V. It's designed for driving bus lines or buffering memory address registers. The three-state outputs provide high impedance when the output enable (OE) input is HIGH, allowing multiple devices to share a common bus. This buffer is useful in applications where data needs to be isolated or driven with higher current.
Applications:
- Memory address buffering
- Bus driving
- Data line isolation
- Backplane driving
- Clock distribution
Features:
- High-speed operation: tpd = 5.0 ns (typ.) at VCC = 5V
- Low power consumption: ICC = 8 μA (max.) at VCC = 5V
- TTL compatible inputs
- Three-state outputs
- Symmetrical output drive: |IOH| = IOL = 24 mA
- Wide operating temperature range: -40°C to +85°C
- Package: SOIC20 (Small Outline Integrated Circuit)
Benefits:
- Fast data transfer in high-speed systems
- Low power consumption contributes to energy efficiency
- Easy integration with TTL logic circuits
- Bus isolation for preventing conflicts
- Directly drives LEDs and other high-current loads
- Suitable for diverse environments
- Surface mount package for compact designs
Additional Details:
The TC74ACT244FT(EL.PP) is fabricated using silicon gate CMOS technology. The device's inputs are equipped with clamp diodes. The 'FT' suffix signifies a surface mount package (SOIC20). 'EL' indicates environmentally friendly lead-free, and PP typically denotes tape and reel packaging. This octal buffer is ideal for applications where bidirectional communication on a bus is required or where a large fan-out is necessary. Each buffer has an independent output enable pin controlling four bits. This provides flexibility in controlling the direction of data flow.
