Overview
The MC74ACT241N is an octal buffer and line driver manufactured by Motorola (now onsemi). It features non-inverting logic with three-state outputs, designed for memory address driving, clock distribution, and bus-oriented transmission. The device operates within a supply voltage range of 4.5V to 5.5V and accepts TTL-compatible inputs. It provides balanced output drive capabilities with source and sink currents of 24mA. The component is housed in a 20-pin plastic dual in-line package (PDIP) and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Octal buffer and line driver architecture providing eight independent non-inverting channels
- Three-state outputs enable direct connection to bus lines without additional drivers
- TTL-compatible input levels simplify interface with legacy digital systems
- High current drive capability supports loading of multiple bus receivers
Applications
- Memory address drivers for high-density PC boards
- Clock signal distribution in digital systems
- Bus-oriented transmitter and receiver circuits
Procurement Notes
Verify the manufacturer designation, as Motorola's semiconductor division was acquired by onsemi. Confirm the specific suffix indicates the PDIP-20 package and industrial temperature grade. Ensure the part number matches the ACT series specifications rather than AC or HC variants. Check for RoHS compliance markings if required by assembly standards.
Selection Notes
Select this component when an octal buffer with three-state control is required for bus applications. It is suitable for designs needing TTL-compatible inputs with CMOS output levels. Consider the PDIP-20 package constraints for through-hole mounting. Verify that the 4.5V to 5.5V supply range aligns with the system power rails.
Part Context
The MC74ACT241N belongs to the 74ACT logic family, which combines the speed of advanced CMOS technology with TTL-compatible inputs. This family is designed for high-speed digital applications requiring low power consumption. The '241' designation specifically identifies the octal buffer configuration with three-state outputs, distinguishing it from inverters or transceivers in the same series.
Replacement Considerations
Equivalent parts include SN74ACT241N from Texas Instruments and MC74ACT241DR2G from onsemi. These alternatives share identical pinouts and functional specifications. Verify package compatibility and temperature ratings before substitution.
