SN74BCT541ANS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT541ANS is an octal buffer and line driver manufactured by Texas Instruments, utilizing state-of-the-art BiCMOS technology. It features non-inverting logic with 3-state outputs controlled by two active-low output-enable inputs (OE1 and OE2). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. Packaged in a 20-pin Small Outline Package (NS), it provides high drive capability with low power consumption characteristics typical of the BCT family.

Buffers, Drivers, Receivers, Transceivers FAQ

How are the 3-state outputs controlled?

The outputs are controlled by two active-low output-enable inputs (OE1 and OE2). If either input is high, all eight outputs enter a high-impedance state.

What is the recommended handling for unused inputs during power-up?

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