Buffer, non-inverting, 3-state — what this part does on the bus
The Texas Instruments SN74HC241PW is a dual 4-bit buffer with non-inverting logic and 3-state outputs in a 20-TSSOP package. It belongs to the 74HC family, operating from 2V to 6V supply, which makes it a direct drop-in for designs that need to isolate or drive a shared bus — address/data lines, control signals, or memory chip-selects — without inverting the signal polarity. Each of the two elements handles four bits independently, and the 3-state output lets you float the bus when the output-enable is inactive, so multiple devices can share the same trace without contention.
Supply range and output drive — what the 2V to 6V and 7.8 mA mean for your BOM
The 2V to 6V supply range covers 3.3V and 5V logic rails without a level translator. If your board runs a 3.3V microcontroller and a 5V peripheral, this buffer can sit on either side — just match VCC to the rail the outputs need to swing. The 7.8 mA source and sink per pin drives one or two standard CMOS loads directly.
Temperature grade and deployment environment
Rated for -40°C to 85°C ambient, the SN74HC241PW suits industrial control panels, outdoor telecom enclosures, and factory-floor equipment where the board sees seasonal temperature swings but not engine-bay or downhole extremes.
Lifecycle and sourcing posture
TI lists the SN74HC241PW as an active product.
