SN74BCT2244N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT2244N is an octal buffer and line/MOS driver with 3-state outputs manufactured by Texas Instruments. It utilizes state-of-the-art BiCMOS design to significantly reduce quiescent current (ICCZ). The device operates within a supply voltage range of 4.5 V to 5.5 V and features high fan-out and improved fan-in capabilities. Outputs include equivalent 33-Ω series resistors to minimize overshoot and undershoot without requiring external components. Each output can source or sink up to 12 mA. The component is housed in a 20-pin PDIP package and supports operation from 0°C to 70°C.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle the high-impedance state during power-up?

To ensure the high-impedance state during power-up or power-down, the OE pin should be tied to VCC through a pullup resistor.

What is the purpose of the internal series resistors in the outputs?

The outputs include equivalent 33-ohm series resistors designed to reduce overshoot and undershoot, eliminating the need for external resistors.
