TIBPAL16L8-15CN – TEXAS INSTRUMENTS

The Texas Instruments TIBPAL16L8-15CN is a 16-macrocell low-power CMOS electrically erasable programmable logic device (EEPROM-based PAL). Operating from a 4.5V to 5.5V VCC supply, it features 16 macrocells, each containing a programmable AND array feeding a configurable OR gate with registered or combinational outputs. The device boasts a typical propagation delay of 15ns (hence the “-15” in the part number), making it suitable for moderately high-speed applications. It’s packaged in a space-saving 20-pin plastic DIP._x000D_

This PAL’s low power consumption is a key advantage, making it ideal for battery-powered or portable systems where minimizing current draw is crucial. The EEPROM-based architecture allows for in-system reprogramming, facilitating field upgrades and design flexibility. Common applications include small-scale glue logic implementations, state machines, code converters, and simple protocol handlers where the relatively limited logic resources are sufficient. Its speed and low power consumption make it a competitive choice compared to larger CPLDs or FPGAs when system complexity doesn’t justify their resource overhead. Designers should note the limited macrocell count; consider larger devices if more logic resources are needed.
