A Comprehensive Guide To TIBPALT19R4CNT * Programmable Logic Device (PLD) IC Macrocells

* Programmable Logic Device (PLD) IC Macrocells

General Description

These programmable array logic devices feature high speed and functionality similar to the TIBPAL16L8，16R4，16R6

16R8 series, but with the added advantage of D-type transparent latches on the inputs. If any input register is not desired

it can be converted to an input buffer by simply programming the architectural fuse. 

Combining Advanced Low-Power Schottky technology, with proventitanium-tungsten fuses, these devices will provide

reliable high performance substitutes over conventional TTL logic. Their easy programmability allows for quick design of

custom functions and typically result in a more compact circuitboard. In addition, chip carriers are available for further

reduction in board space.

Extra circuitry has been provided to allow loading of each register asynchronously to either a high or low state. This

feature simplifies testing because the registers can be set to an initial state prior to executing the test sequence.

A C suffix designates commercial-temperature circuits that are characterized for operation from 0℃ to 70℃.

Features

• High-Performance Operation ...30 MHz

• Preload Capability on Output Registers

• DIP Options Include Both 300-mil Plastic and 600-mil Ceramic

• Dependable Texas Instruments Quality and Reliability
