What are the key features of TIBPAL16L8-7CN?
- PAL-type architecture with 64 product terms and 16 inputs enables flexible combinational logic implementation replacing multiple standard gate ICs
- Bipolar process delivers 7 ns propagation delay for high-speed glue logic in address decoding and bus control applications
- 20-pin PDIP package with 10 dedicated inputs and 6 bidirectional I/O lines suits prototyping and legacy board repair without PCB redesign
What is TIBPAL16L8-7CN used for?
TIBPAL16L8-7CN is used in legacy embedded systems, industrial controllers, and custom logic boards for address decoding, bus arbitration, and glue logic consolidation in 5 V TTL environments. Its PAL architecture allows field-programmable combinational logic replacing up to 6 discrete 74-series gates in a single 20-pin PDIP footprint, reducing board complexity in repair and maintenance of older equipment.

Frequently Asked Questions
What is the propagation delay of TIBPAL16L8-7CN and how does it compare to standard 74-series gates?
TIBPAL16L8-7CN achieves a propagation delay of 7 ns, which is comparable to fast 74AS-series gates and significantly faster than 74LS gates at 15 ns to 20 ns. This makes it suitable for high-speed address decoding and combinational glue logic in 5 V TTL systems operating above 50 MHz bus frequencies.
How many logic equations can be implemented in TIBPAL16L8-7CN and what determines the complexity limit?
TIBPAL16L8-7CN supports 64 product terms distributed across 8 output macrocells, with each output typically supporting up to 8 product terms in a sum-of-products form. This allows implementation of address decoders with up to 16 inputs, bus enables, state machine outputs, or combinations of simple Boolean functions covering common glue logic scenarios.
Is TIBPAL16L8-7CN still available for replacing failed PAL devices in legacy industrial equipment?
Yes, TIBPAL16L8-7CN is available in stock in the standard 20-pin PDIP-600 mil wide body package, making it a direct physical replacement for failed PAL16L8 devices in legacy industrial panels, CNC controllers, and VME/STD bus boards from the 1980s and 1990s. The JEDEC-standard fuse map ensures compatibility with original programming files.
