Applications
The TIBPAL16R4-25CN is widely used in legacy industrial control, telecom line cards, and test equipment where compact glue logic and synchronous state machines are needed. Typical designs include address decoders, bus arbiters, counters, and protocol converters that benefit from a single programmable IC replacing many SSI/MSI parts. It also remains popular for long-life embedded systems and field repair of older boards still in production.

Frequently Asked Questions
What is the maximum clock frequency of the TIBPAL16R4-25CN?
The TIBPAL16R4-25CN supports a maximum clock frequency of 30 MHz on its registered outputs, making it suitable for synchronous state machines, counters, and control logic that need deterministic timing in legacy and industrial designs.
How many inputs and outputs does the TIBPAL16R4-25CN provide?
It is a PAL-type device with 8 dedicated input pins, 12 total inputs into the AND array, 4 registered outputs, and 4 combinatorial I/O lines, all housed in a 20-pin R-PDIP-T20 dual-in-line package for easy through-hole assembly.
Is the TIBPAL16R4-25CN lead-free and RoHS compliant?
Yes. The TIBPAL16R4-25CN carries the Pb-free code Yes and a JESD-609 e4 lead-finish classification, so it is lead-free and compatible with RoHS-compliant manufacturing flows including standard SnAgCu reflow and wave soldering.
What package does the TIBPAL16R4-25CN use and is it through-hole or surface-mount?
The part is supplied in a 20-pin plastic dual-in-line (R-PDIP-T20) package, which is a through-hole DIP. This makes it easy to socket for prototyping and convenient for repairing legacy boards that already use DIP-20 PAL devices.
Where can I buy the TIBPAL16R4-25CN and what is the typical price?
FindMyChip lists the Texas Instruments TIBPAL16R4-25CN from $2.688 per unit with global stock and worldwide shipping. Pricing varies with quantity and packaging, and bulk or reel options can be quoted on request for production runs.
