SN74HC540PWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC540PWT is an octal buffer and line driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V, providing inverted data at the outputs. The device features high-current 3-state outputs capable of driving bus lines directly or up to 15 LSTTL loads. It utilizes a data flow-through pinout arrangement where all inputs are located on the opposite side from the outputs, facilitating printed circuit board layout. The package type is TSSOP-20.

Data flow-through pinout with inputs and outputs on opposite sides

Buffers, Drivers, Receivers, Transceivers Applications

Bus-oriented systems
Clock buffering and distribution
Memory module address/data bus drivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PWT' corresponds to the TSSOP-20 package configuration. Confirm the component status as Obsolete in current production lists and check for active alternatives like SN74HC540PWR if long-term availability is required. Ensure RoHS compliance matches project specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with 3-state control is needed for 2 V to 6 V logic families. The TSSOP-20 package is suitable for surface-mount applications requiring space efficiency. Consider the high output drive capability for direct interfacing with buses or multiple loads without additional amplification stages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4HC540 family of octal buffers and line drivers. It shares functional similarities with the popular 'HC240 series but offers a distinct pinout arrangement that simplifies PCB routing. The HC540 devices provide inverted data at the outputs controlled by two output-enable inputs via a 2-input NOR gate.
