TIBPAL20L8-10C, TIBPAL20R4-10C, TIBPAL20R6-10C, TIBPAL20R8-10C are Texas Instruments' high-performance IMPACT-X PAL circuits. They feature high speed and functional equivalency when compared with currently available devices. These IMPACT-X circuits combine low power consumption, small size and high speed.
The TIBPAL20 series PAL devices are high‑performance IMPACT‑X™ logic circuits offering fast operation, preload capability on output registers, and power‑up clear of registered outputs. The handbook provides functional block diagrams, pin‑assignment tables for JT and NT packages, and details on package options such as plastic chip carriers and ceramic DIPs.
Key specifications include maximum operating frequencies, propagation delay, temperature range, and fuse technology. Production data, warranty information, and TI North American sales contacts are also listed for design engineers and distributors.
