Each of the two 4-bit elements can sink or source 24 mA per output, making it a solid choice for driving address or data buses on legacy 5 V backplanes, or for buffering control signals in industrial PLC I/O modules. ## Package and mounting The 24 mA symmetric output drive handles standard TTL fan-out of ten loads or drives a 5 V relay coil with a series resistor. At 5 V supply, the 3-state outputs float to high impedance when the output-enable pins are asserted, letting multiple buffers share a bus without contention. The 74ACT family's faster edge rates compared to 74LS mean you should keep trace lengths under a few inches to avoid ringing — a 33 Ω series resistor at each output cleans that up on a prototype. ## Active lifecycle — no LTB scramble The through-hole DIP package is socket-friendly, which matters for field-service swaps — you can pull a failed buffer and seat a replacement without a hot-air station.","metaTitle":"CD74ACT241E 74ACT Octal Buffer, 3-State, 20-DIP, Active","metaDescription":"CD74ACT241E 74ACT octal non-inverting buffer with 3-state outputs, 24 mA drive, 4.5V–5.5V supply, –40°C to 85°C, 20-PDIP.
