Frequently Asked Questions
How many enable inputs does the CD74HC154EE4 have?
The CD74HC154EE4 has two active-low enable inputs (E1 and E2), both of which must be LOW for the device to decode and activate any output. This dual-enable feature allows easy cascading of multiple decoder ICs for larger address space decoding and provides convenient chip-select control in system designs.
What is the logic function and output count of the CD74HC154EE4?
The CD74HC154EE4 is a 4-line to 16-line decoder, accepting a 4-bit binary address input and asserting one of 16 active-low output lines corresponding to the binary value. With a maximum output low current of 4 mA, it can directly drive standard CMOS and TTL-compatible logic inputs.
What package does the CD74HC154EE4 come in?
The CD74HC154EE4 is housed in a 24-pin plastic dual-in-line (PDIP) through-hole package, designated R-PDIP-T24. The PDIP format is ideal for prototyping and legacy through-hole PCB designs, fitting standard 0.6-inch DIP sockets that are common in digital logic development and educational lab boards.
Is the CD74HC154EE4 RoHS compliant?
Yes, the CD74HC154EE4 is marked with Pb-free (lead-free) status and carries a JESD-609 code of e4, indicating compliance with RoHS environmental requirements. This makes it suitable for use in modern electronic products requiring adherence to EU RoHS and similar environmental standards.
