22V10ACFNSX

The 22V10ACFNSX belongs to TIBPAL22V10 and TIBPAL22V10A family which are programmable array logic devices featuring high speed and functional equivalency when compared to presently available devices and they are implemented with the familiar sum-of-products (AND-OR) logic structure featuring the new concept "Programmable Output Logic Macrocell". A power-up clear function is supplied that forces all registered outputs to a predetermined state after power is applied to the device. Registered outputs selected as active-low power up with their outputs high. Registered outputs selected as active-high power up with their outputs low. A single security fuse is provided on each device to discourage unauthorized copying of fuse patterns. Once blown, the verification circuitry is disabled and all other fuses will appear to be open. The TIBPAL22V10C and TIBPAL22V10AC are characterized for operation from 0°C to 75°C. The TIBPAL22V10AM is characterized for operation over the full military temperature range of 55°C to125°C. These 22V10ACFNSX IMPACT circuits combine the latest Advanced Low-Power Schottky technology with proven titanium-tungsten fuses to provide reliable, high-performance substitutes for conventional TTL logic. 22V10ACFNSX contain up to 22 inputs and 10 outputs. They incorporate the unique capability of defining and programming the architecture of each output on an individual basis. Outputs may be registered or nonregistered and inverting or noninverting as shown in the output logic macrocell diagram. The ten potential outputs are enabled through the use of individual product terms.

The features of 22V10ACFNSX can be summarized as (1)second-generation PLD architecture; (2)choice of operating speeds TIBPAL22V10AC: 25 ns Max, TIBPAL22V10AM: 30 ns Max, TIBPAL22V10C: 35 ns Max; (3)increased logic power up to 22 inputs and 10 outputs; (4)increased product terms average of 12 per output; (5)variable product term distribution allows more complex functions to be implemented; (6)each output is user programmable for registered or combinational operation, polarity, and output enable control; (7)TTL-level preload for improved testability; (8)extra terms provide logical synchronous set and asynchronous reset capability; (9)fast programming, high programming yield, and unsurpassed reliability ensured using Ti-W fuses; (10)AC and DC testing done at the factory utilizing special designed-in test features; (11)dependable texas instruments quality and reliability; (12)package options include both plastic and ceramic chip carriers in addition to plastic and ceramic DIPs; (13)functionally equivalent to AMDs AMPAL22V10 and AMPAL22V10A.
