Toshiba Non-Inverting 3 State Octal Bus Buffer 20-Pin SOIC 2V to 6V 74HC244D

Toshiba 74HC244D Non-Inverting 3 State Octal Bus Buffer 20-Pin SOIC operates with a supply voltage range from 2 V to 6 V and delivers balanced propagation delays approximately equal in rise and fall times. Fabricated using silicon gate C2MOS technology, this device combines high speed operation similar to LSTTL devices with the advantage of CMOS low power dissipation.

All inputs incorporate protection against static discharge and transient excess voltage, enhancing device reliability in industrial and computing environments.

This octal bus buffer provides a maximum propagation delay time of 165 ns under capacitive load, suitable for high-speed data handling requirements. It can handle a maximum output high level current of -7.8 mA, and output low level current of 7.8 mA, making it ideal for interfacing with TTL inputs and other logic families.

The device operates over a broad temperature range from -40°C to 85°C, supporting industrial and automotive applications where temperature robustness is critical. Its 20-pin SOIC surface-mount package, measuring 13.1 mm in length and 2.25 mm in height, allows for compact PCB layout and automated assembly.

Key features include balanced propagation delays (tPLH ≈ tPHL), low standby current dissipation (ICC max 4.0 µA at 25°C), and wide operating voltage range from 2.0 V to 6.0 V. These characteristics ensure efficient and reliable logic buffering in embedded systems, communication equipment, and other electronic circuits.

Operates within 2 V to 6 V supply voltage range. Non-inverting 3-state outputs with two active-low enables. CMOS input type with silicon gate C2MOS technology. 20-pin SOIC surface mount packaging for space-saving design.

High speed with typical 10 ns propagation delay at 6 V supply. Wide operating temperature from -40°C to 85°C. Robust input protection against static and transient voltages. This product is ideal for industrial, electronic system design, computing, and communication applications requiring efficient bus buffering and signal isolation.
