What are the key features of 74AC11257PWE4?
- Quad 4-channel 2-to-1 multiplexer in 20-pin TSSOP enabling compact bus and data routing with a shared select line
- 24 mA maximum output sink current (I_OL) supporting direct bus driving in AC-family CMOS logic at standard supply voltages
- REACH-compliant and e4 lead-free (JESD-609) construction in R-PDSO-G20 TSSOP package for modern RoHS designs
What is 74AC11257PWE4 used for?
74AC11257PWE4 is used in data bus routing, address multiplexing, and source selection circuits where 4 pairs of signals must be switched between two sources using a single select pin. It is well suited for FPGA and CPLD I/O expansion boards, test multiplexer arrays, and memory address bus expansion in embedded systems requiring AC-speed switching. The TSSOP-20 package minimizes PCB footprint in dense logic boards compared to wider SOIC alternatives.

Frequently Asked Questions
Which designs are a good fit for 74AC11257PWE4 with 24 mA?
74AC11257PWE4 fits industrial, embedded, and repair-oriented electronic assemblies when the design needs 24 mA and 0.024 A. It is a practical choice when the BOM also matches the 20-pin TSSOP footprint.
How should engineers check package compatibility for 74AC11257PWE4?
Compare the PCB land pattern, height allowance, and assembly process against the 20-pin TSSOP style. The 20 pins detail is the first check before approving a replacement.
What matters when sourcing 74AC11257PWE4 as a replacement?
Confirm the same 24 mA, 0.024 A, manufacturer traceability, and lifecycle status before substituting it. Buyers should also verify stock for the exact 20-pin TSSOP configuration.
