SN74BCT541ADB

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT541ADB is an octal buffer and line driver featuring three-state outputs, manufactured using state-of-the-art BiCMOS technology. It 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. The device provides high drive capability with low-level output currents up to 64 mA and high-level output currents up to -15 mA. Propagation delays are specified at a maximum of 8.2 ns for tPHL and 6 ns for tPLH at 5 V. Inputs utilize P-N-P structures to reduce DC loading.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features inputs and outputs on opposite sides of the package to facilitate printed-circuit-board layout.
• Includes two active-low output-enable (OE) inputs that place all outputs in a high-impedance state when asserted.
• BiCMOS design significantly reduces quiescent current compared to standard CMOS equivalents.
