SN74HC541NE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC541NE4 is an octal buffer and line driver from the Texas Instruments 74HC logic family. It features eight non-inverting outputs with three-state capability, controlled by dual output enable inputs. The device operates within a supply voltage range of 2 V to 6 V. It utilizes a 20-pin plastic dual in-line package (PDIP). Key electrical characteristics include a high-level output current of -7.8 mA and a low-level output current of 7.8 mA. The quiescent current is typically 8 µA. The component supports an operating temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix NE4 indicates the lead-free PDIP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the ordering part number matches the required package style and environmental specifications for your assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring octal buffering with tri-state bus control capabilities. It serves as a suitable replacement for older 74LS541 devices where lower power consumption is necessary. Consider the PDIP-20 package constraints regarding board space and thermal dissipation compared to surface-mount alternatives like SOIC or TSSOP variants.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the widely adopted 74HC series of high-speed CMOS logic devices manufactured by Texas Instruments. The 74HC541 specifically addresses the need for multi-bit data direction control and signal conditioning. It represents a standard solution for interfacing between different logic families or managing data flow on shared system buses.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents include the SN74HC541N without the E4 suffix, which denotes the same PDIP-20 configuration. Other package variations such as SN74HC541DWR (SOIC) or SN74HC541PWR (TSSOP) offer identical logical functionality but require different footprint considerations during PCB layout adaptation.
