SN74BCT540AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT540AN is an octal buffer and line driver manufactured by Texas Instruments, belonging to the BCT logic series. It features eight inverting inputs and outputs housed in a 20-pin PDIP package. The device operates on a single power supply ranging from 4.5 V to 5.5 V with a typical quiescent current of 71 uA. It provides three-state outputs capable of sourcing -15 mA at high levels and sinking 64 mA at low levels. Propagation delay is specified at 5.8 ns at 5 V. It functions within a commercial temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent inverting buffer channels for parallel data handling.
• Three-state output architecture enabling bus-oriented applications with controlled signal isolation.
• BiCMOS technology implementation ensuring high-speed performance with low static power consumption.

• Bus-oriented memory and address drivers
• Clock drivers and buffering
• Control signal routing in digital systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'AN' corresponds to the PDIP-20 through-hole package variant. Confirm RoHS compliance status via the manufacturer's official documentation, as environmental declarations may vary by production batch. Ensure the application voltage remains within the 4.5 V to 5.5 V range to maintain specified electrical characteristics and avoid exceeding absolute maximum ratings.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-drive capability with significant low-level sink current (64 mA) for robust signal integrity. The BCT series offers a balance between speed and power efficiency compared to standard TTL or CMOS alternatives. Consider the PDIP-20 package constraints if space is limited, as surface-mount variants like the DW or NSR suffixes may be required for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74BCT family, which utilizes BiCMOS technology to achieve performance levels comparable to advanced logic families while maintaining compatibility with standard 5 V logic interfaces. The 540 designation specifically identifies the octal buffer/driver topology with three-state outputs, distinguishing it from non-inverting counterparts or different channel counts within the same logical family.
