SN74HC241PW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC241PW 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. The device features high-current outputs capable of driving up to 15 LSTTL loads, with typical propagation delay of 11 ns at 4.5 V. It consumes low power, with maximum ICC of 80 μA. The component is housed in a 20-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix and package type against the manufacturer's current orderable addendum. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure the selected variant matches the required operating temperature range and thermal resistance specifications for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with 3-state capabilities. Consider the 2 V to 6 V operating voltage range and the requirement for separate output-enable controls. Evaluate the thermal performance characteristics associated with the TSSOP-20 package for adequate heat dissipation in the target circuit design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4HC241 family of octal buffers and line drivers with 3-state outputs. The 'HC' designation indicates High-speed CMOS technology. The PW suffix specifically denotes the TSSOP (Thin Shrink Small Outline Package) with 20 pins, distinguishing it from other package options like SOIC or PDIP available within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74HC241PWR is an active production alternative in the same TSSOP-20 package. Other package variants such as SN74HC241DW (SOIC) or SN74HC241N (PDIP) offer functional equivalence but require different footprint considerations on the printed circuit board.

Buffers, Drivers, Receivers, Transceivers FAQ

How are the outputs controlled?

The device is organized as two 4-bit buffers with separate output-enable inputs (1OE and 2OE). When an enable input is low, the respective outputs pass non-inverted data; when high, they enter a high-impedance state.

What is the recommended bypass capacitor value?

A 0.1-μF capacitor is recommended for each VCC terminal to prevent power disturbance. It should be installed as close to the power terminal as possible.
