Frequently Asked Questions
What logic family does the CD74ACT541SM96E4 belong to and what are its voltage levels?
The CD74ACT541SM96E4 belongs to the ACT (Advanced CMOS TTL-compatible) logic family. It accepts TTL-level inputs and produces CMOS output levels while operating from a 5V supply. This dual compatibility makes it ideal for interfacing between CMOS logic devices and legacy TTL bus drivers or microprocessors in mixed-logic system designs.
How do the output enable pins work on the CD74ACT541SM96E4?
The CD74ACT541SM96E4 has two active-low output enable inputs (1OE and 2OE). When both are LOW, all eight outputs are actively driven. When either OE pin is HIGH, all outputs enter the high-impedance (tri-state) mode, disconnecting them from the bus. This allows the device to be used in bus-sharing configurations without signal contention between multiple drivers.
What package does the CD74ACT541SM96E4 use?
The CD74ACT541SM96E4 is packaged in a 20-pin SSOP (Shrink Small Outline Package), JESD-30 code R-PDSO-G20. This compact surface-mount package offers a smaller footprint than standard SOIC while maintaining compatibility with automated assembly equipment, making it suitable for high-density PCB designs in data communications and industrial control applications.
What is the maximum output current capability of the CD74ACT541SM96E4?
The CD74ACT541SM96E4 can sink up to 24 mA per output (I_ol maximum), which enables it to drive standard TTL loads, LEDs, and other moderate-current devices directly from its output pins. The 50 pF rated load capacitance also ensures it can maintain signal integrity across typical bus wiring lengths found in embedded system backplanes.
