CS82C82 - CMOS Octal Latching Bus Driver | Intersil
料号： CS82C82 ✗ 停产CS82C82 概述
What is a CMOS octal latching bus driver? This component class combines bidirectional or uni-directional digital buffering with storage or control logic so that a processor, memory, or peripheral can exchange eight parallel signals while preserving timing, drive strength, or bus isolation. In a larger system hierarchy, the CS82C82 belongs to logic ICs, then interface ICs and bus-interface logic, rather than to a processor, memory device, or analog signal chain.
The primary verified feature is its eight-bit parallel latch/buffer organization. The CS82C82 is identified as a CMOS octal latching buffer manufactured using a self-aligned silicon-gate CMOS process. Its package is listed as PQCC20 in one distributor result and as a 20-PLCC (9x9) package by DigiKey. The verified data does not provide verified supply-voltage values, output-current ratings, propagation delays, input/output logic levels, quiescent current, or timing limits, so those parameters are not inferred here.
The CS82C82 is suited to legacy digital systems requiring an eight-channel registered bus interface, especially where the existing PCB uses the specified 20-pin package and the surrounding logic expects the CS82C82's pin arrangement. Its CMOS implementation and true-output designation make it more relevant to conventional digital bus interconnection than to high-speed differential, RF, or analog applications.
Typical design work focuses on correct data and latch-control timing, signal-state compatibility, input-output direction requirements, and package-level PCB layout. Engineers should verify the manufacturer datasheet and the specific Harris/Intersil source before production use because the supplied search data does not include a complete electrical parameter table or an official manufacturer product-page URL.
This page summarizes the verified CS82C82 identity, package, logic category, and sourcing references. It also separates documented facts from unavailable parameters and explains why no drop-in alternatives are asserted without verified pin and electrical equivalence.

典型应用
CS82C82 适用于 6 应用s: Legacy parallel-bus isolation, Processor-to-peripheral data buffering, Industrial control logic, Data-acquisition interface, Test and measurement control, Embedded communication equipment.
Legacy parallel-bus isolation
The CS82C82 fits a legacy parallel-bus isolation point when the design needs an eight-channel CMOS latch or buffer between two digital logic sections. Its verified eight-bit organization and 20-pin PLCC/PQCC20 package make it relevant to systems that already depend on the original pin arrangement. The value of this application is architectural rather than high-speed: the device can organize and register parallel signals, but the supplied data does not verify propagation delay, drive current, or supply voltage, so timing and electrical compatibility must be confirmed from the original datasheet.
推荐
Processor-to-peripheral data buffering
The CS82C82 can serve as an eight-bit data-path element between a processor-side bus and a peripheral interface in an established CMOS logic design. Its latching-buffer description helps preserve a parallel data word while the surrounding circuitry manages control sequencing. Because the verified sources do not provide logic thresholds, timing limits, or power rails, this use should be limited to designs with an existing, documented CS82C82 interface and should not be treated as a universal modern bus substitute.
推荐
Industrial control logic
The CS82C82 may be suitable in an industrial control system that retains an older eight-bit parallel logic architecture, particularly where a PLCC package and established board footprint are already fixed. The part’s CMOS octal latching-driver description supports digital signal conditioning within the legacy architecture. However, the verified data contains no industrial temperature rating, isolation rating, EMC qualification, or lifecycle statement, so it must not be assumed to meet current industrial safety or reliability requirements without manufacturer documentation.
推荐
Data-acquisition interface
In a data-acquisition system, the CS82C82 can provide a parallel latch or buffer stage for eight digital control or status signals associated with an older acquisition architecture. Its eight-bit structure may simplify the connection between a bus master and peripheral logic when the original interface is already designed around the CS82C82. The supplied data does not verify noise, timing, supply voltage, or input-output levels, so analog front-end performance and sampling timing must remain independent design constraints rather than assumed benefits of this driver.
推荐
Test and measurement control
The CS82C82 is relevant to test and measurement equipment that uses an eight-bit parallel control bus and retains a legacy CMOS logic board. The latch or buffer function can help organize control signals between an instrument controller and front-panel or peripheral circuitry. The verified material does not establish input impedance, noise, output drive, settling time, or operating temperature, so the device should be used only where the original design’s electrical timing and loading requirements are already known and documented.
推荐
Embedded communication equipment
The CS82C82 can support an older embedded communication chassis where eight parallel signals are buffered or latched between controller and interface logic. Its verified one-function, eight-bit, true-output description makes it a specialized bus-interface element rather than a transceiver or protocol device. When paired with a separately selected communication controller, the CS82C82 may fit a legacy parallel command, status, or data path, but supply voltage, timing, and package compatibility must be confirmed against the original equipment documentation.

设计说明
Do not substitute an octal latch solely by its logic description. Confirm the exact CS82C82 pinout, data-line directions, latch-control polarity, supply pins, ground pins, input thresholds, output levels, and timing before approving a replacement. The verified search results confirm the 20-pin PLCC/PQCC20 package and eight-bit latching-buffer function, but they do not provide a complete pin table or electrical parameter table.
Preserve the original 20-pin PLCC footprint and verify pin-one orientation, lead pitch, body clearance, and solder-process compatibility against the actual package drawing. PLCC parts can be sensitive to assembly rework and thermal cycling, so the board layout should follow the manufacturer’s land pattern and handling guidance. Do not derive a footprint from the abbreviated PQCC20 label alone.
Before connecting the CS82C82 to a system, verify its supply-voltage range, input thresholds, output levels, and current limits from the applicable Harris/Intersil datasheet. Those values are absent from the supplied search snippets and must not be inferred from generic CMOS assumptions. Check that the upstream rail, downstream loads, pull networks, and control-signal levels satisfy the verified limits.
Treat the latch-enable and data timing as a complete interface contract. Establish setup and hold requirements, propagation delay, load capacitance, and bus-transition expectations using the original timing table. The verified data identifies the CS82C82 as a CMOS octal latching bus driver, but it does not provide timing values, so simulation or measurement is required when the application depends on precise control-edge behavior.
Do not treat a distributor or datasheet-search listing as proof of current availability, price, lifecycle status, or compliance. The supplied references establish the product category and package, while current stock, numeric pricing, RoHS, REACH, temperature, and lifecycle values remain unverified. Procurement and engineering release should therefore use a current authorized-distributor record and the applicable manufacturer documentation.
合规信息
The supplied search results do not provide verified RoHS, REACH, lead-free, halogen-free, conflict-mineral, or automotive-qualification data. The CS82C82 is treated as a general-purpose legacy CMOS logic IC because no AEC-Q100 claim appears in the supplied data.
