Frequently Asked Questions
What is the SN74CBT3253CPWR and what does it do?
The SN74CBT3253CPWR is a dual 4-to-1 FET bus switch multiplexer/demultiplexer from Texas Instruments. It allows bidirectional routing of signals between a common bus and one of four selectable channels, with TTL-compatible control inputs and an active-low enable pin. It operates with a 50pF load capacitance and is housed in a 16-pin SOIC package.
What are the key electrical specifications of the SN74CBT3253CPWR?
Key specs include bidirectional switching, TTL-compatible control inputs, active-low enable, 50pF load capacitance, and a JESD-30 package code of R-PDSO-G16 (16-pin SOIC). The device is part of the CBT/FST/QS/5C/B logic family and is fully Pb-free (JESD-609 code e4), with a 15-year estimated time of obsolescence (YTEOL).
What are typical applications for the SN74CBT3253CPWR?
This device is commonly used in memory bank selection, CPU-to-peripheral bus expansion, and multi-channel signal multiplexing in embedded systems. It is also suitable for communication interfaces, industrial control boards, and test equipment where flexible, low-power bus switching between multiple signal sources is needed.
What package does the SN74CBT3253CPWR come in and are there compatible alternatives?
The SN74CBT3253CPWR is available in a 16-pin Small Outline (SOIC/PDSO) surface-mount package. Compatible alternatives within the Texas Instruments CBT family include other dual 4-to-1 bus switches in similar pinouts. Always verify electrical and timing specifications before substituting parts in a design.
