The 74HCT241PW/C4118 is a dual 4-bit buffer with non-inverting outputs and 3-state control, built in the 74HCT logic family. Each of the two elements handles four bits, and the 3-state outputs let you share a bus with other devices — pull the output-enable pins high and the outputs go high-impedance, effectively disconnecting from the bus. The 20-TSSOP package is a fine-pitch surface-mount footprint (0.173" body width, 4.40 mm), so plan for hot-air rework if you need to swap it on a board.
Output drive and bus interface
The 3-state control is straightforward: two enable pins (one active-low, one active-high per the 74HCT241 function table) let you isolate the outputs when the bus is owned by another driver. If you are replacing a 74HC241, note that the HCT variant has TTL-level input thresholds (0.8 V low, 2.0 V high) versus the HC's CMOS thresholds (0.3 × VCC, 0.7 × VCC). In a 5 V system with 5 V logic, both work; if your upstream driver is a 3.3 V part with 5 V-tolerant outputs, the HCT's lower input-low threshold can give you a bit more noise margin on the falling edge.
