Frequently Asked Questions
What does the CD74ACT240M96E4 do and how is it enabled?
The CD74ACT240M96E4 is an octal inverting bus driver that passes inverted logic signals from its eight inputs to eight 3-state outputs. It is enabled by two active-low output enable (OE) pins that when asserted allow the inverted outputs to drive a bus. When either OE is deasserted (high), all outputs enter a high-impedance state, disconnecting the driver from the bus.
What is the output drive current of the CD74ACT240M96E4?
The CD74ACT240M96E4 belongs to the ACT logic family and provides high output drive capability with TTL-compatible voltage levels. Its maximum output sink current (I(ol)) is specified at the ACT standard level with 50pF load capacitance used for timing characterization. This drive strength makes it suitable for driving PCB traces with multiple receiver inputs in bus-oriented digital systems.
What is the M96 suffix in CD74ACT240M96E4?
The M96 suffix refers to the specific package variant: a 20-pin wide-body SOIC (Small Outline IC) in a 96-position tape-and-reel format for automated assembly. The E4 suffix indicates the device is lead-free and RoHS compliant per JESD-609 code e4. This packaging is optimized for high-volume surface-mount manufacturing with standard pick-and-place equipment.
Why would a designer choose the inverting CD74ACT240 over the non-inverting CD74ACT244?
A designer would select the CD74ACT240M96E4 inverting buffer when the downstream logic requires complemented signals, such as when interfacing with active-low enable inputs or when the signal polarity must be matched to the receiver's logic convention. The CD74ACT244 provides non-inverted buffering for direct signal replication. Both have identical pinouts except for the inversion function, allowing easy substitution.
