The TC74AC244FW from Toshiba is an advanced, high-speed CMOS octal bus buffer designed for applications such as 3-state memory address drivers. Fabricated with silicon gate and double-layer metal wiring C2MOS technology, it achieves high-speed operation comparable to bipolar Schottky TTL while maintaining low CMOS power dissipation.
This non-inverting buffer features 3-state outputs and two active-low output enables. Key electrical characteristics include a typical propagation delay of 4.0 ns at 5V, a wide operating voltage range from 2V to 5.5V, and symmetrical output impedance capable of driving 50 Ω transmission lines. The device also boasts high noise immunity and low power consumption, with a maximum quiescent current of 8 µA at 25°C.
The TC74AC244FW is supplied in a 20-pin SOP (Small Outline) package with gull wing leads and a terminal pitch of 1.27 mm, suitable for surface mounting. Its inputs are protected against static discharge and transient excess voltage, ensuring reliability in various operating conditions. This buffer is pin and function compatible with 74F240/244 series.
The device operates from 2V to 5.5V, with a nominal supply of 5V.
The operating temperature range is from -40°C to 85°C.
It is available in a SOP-20 (0.300 inch plastic) surface-mount package.
Typical propagation delay is 4.0 ns at 5V supply, with a maximum of 8.5 ns.
Maximum quiescent current is 8 µA at 25°C.
It can source or sink 24 mA minimum per output.
