CS82C86H جائزہ

The Texas Instruments CS82C86H is an 8-bit bidirectional CMOS bus transceiver designed for 4.5 V to 5.5 V systems and housed in a 20-lead PLCC package measuring 9 mm by 9 mm. It provides an industry-standard 8286-compatible pinout, supports 20 mA bus sink current, and uses a self-aligned silicon-gate CMOS process identified as Scaled SAJI IV.

A bus transceiver is an interface IC that connects two digital systems while allowing data to travel in either direction. Its functional hierarchy is octal transceiver, bidirectional transceiver, bus-interface logic IC, interface IC, and semiconductor. The CS82C86H combines eight data lines with direction and output-enable control, allowing a processor or bus controller to drive a shared bus or receive data from it without changing the board layout.

Key features include a complete eight-bit bidirectional data interface, an 8286-compatible pin arrangement, 20 mA output-low drive capability on the B side, 8 mA input-high current, and operation across a 4.5 V to 5.5 V supply range. The PLCC-20 surface-mount package supports compact legacy computer, industrial-control, and embedded bus-interface designs while retaining readily identifiable logic functions.

The device was originally documented by Intersil and Harris and is associated with the CS82C86 family. Its direction-control architecture requires the system to assert the transmit-enable state before the transceiver actively drives the bus and deassert it before changing direction. Because the output driver can source and sink bus current, external termination, pull-up, or pull-down components may influence signal integrity and must be selected from the circuit-level requirements rather than assumed universally.

Typical uses include bidirectional processor and peripheral data buses, memory-interface control, industrial acquisition equipment, and legacy computer backplanes. The 8286-compatible arrangement simplifies migration among bus-interface components that use the same directional and enable conventions. Systems should still validate timing, drive strength, and termination because a common pinout does not guarantee identical propagation delay or output characteristics among every device in the 8286-compatible ecosystem.

For robust implementation, connect the data pins only to compatible bus nodes, define DIR and OE states during reset so no device contests the bus, and use pull-up resistors where the bus requires a defined idle state. Confirm signal polarity and timing in the manufacturer's data sheet before replacing a part in an existing two-board system. Avoid using a package with a different lead arrangement unless the PCB footprint and pin assignment have been independently verified.

This product page combines the device family description, package information, interface features, procurement guidance, and practical bus-layout considerations. It also distinguishes verified functions from parameters that must be checked in the original manufacturer data sheet before timing closure, replacement qualification, or high-volume PCB release.

عام استعمالات

CS82C86H کے لیے موزوں ہے 6 ایپلیکیشنs: Legacy Processor Bus Interface, Peripheral Data-Bus Buffering, Industrial Acquisition Backplane, Memory Interface Control, Computer Backplane Communication, Communications Module Interconnect.

🖥️

Legacy Processor Bus Interface

The CS82C86H fits a legacy 5 V processor bus that requires eight data lines to operate as a single bidirectional port. Its documented 4.5 V to 5.5 V supply range, 20 mA B-side output-low capability, and 8286-compatible control arrangement allow the device to sit between a controller and a shared bus. DIR selects transmit or receive operation, while OE disables the drivers during reset and bus arbitration. The original manufacturer timing characteristics must be used to establish setup, hold, and propagation margins rather than inferred from the bus width alone.

🔧

Peripheral Data-Bus Buffering

The CS82C86H is appropriate for isolating a peripheral data port from a wider shared bus while preserving bidirectional communication. Its eight parallel channels reduce the number of separate buffers needed for byte-wide data paths, and the PLCC-20 package provides a compact surface-mount footprint. Engineers should assign DIR and OE states so that the peripheral cannot contend with another bus master. Pull-up or pull-down components should be placed close to the transceiver when the bus requires a defined inactive level.

🏭

Industrial Acquisition Backplane

The CS82C86H can support bidirectional data transfer between an acquisition controller and a backplane in a 5 V industrial system. Its eight-bit architecture suits byte-wide control and measurement buses, while the 20 mA B-side sink-current specification provides useful drive capability for conventional CMOS loading. Board-level signal integrity still depends on bus length, topology, termination, and the number of connected loads. Use short branches and validate ringing and setup time in the complete system rather than relying only on component-level timing.

💾

Memory Interface Control

The CS82C86H can be used as the directional bus element in older memory-control architectures where address, data, and control paths are divided among several devices. The eight bidirectional lines provide a byte-wide data interface, while DIR and OE allow the system to prevent simultaneous driving from more than one source. Care is required around memory read and write turnaround because the control sequence must guarantee adequate dead time before direction changes. Consult the manufacturer data sheet for the exact propagation-delay and timing values used in the original design.

🌐

Computer Backplane Communication

The CS82C86H matches the functional needs of legacy computer backplanes that distribute byte-wide bidirectional signals among several modules. Its 8286-compatible arrangement supports predictable integration with compatible bus-interface logic, and the PLCC-20 package provides 20 leads in a 9 mm by 9 mm body. Backplane implementations must account for signal reflections, bus topology, load capacitance, and clock-skew tolerance. Direction and output-enable control should remain deterministic during power-up, reset, and fault-recovery states.

📡

Communications Module Interconnect

The CS82C86H can serve as a parallel interface element in older communications equipment that exchanges byte-wide control or payload data with a host processor. Its bidirectional channel count reduces the number of discrete bus-driver packages, and the 4.5 V to 5.5 V operating range matches 5 V CMOS logic systems. The design should disable outputs during reset, keep control traces away from sensitive analog paths, and use termination appropriate to the physical bus. Signal-integrity and timing verification must include the complete interconnect rather than the transceiver alone.

What is the CS82C86H?

The CS82C86H is an 8-bit bidirectional CMOS bus transceiver operating from 4.5 V to 5.5 V in a 20-lead PLCC package. According to the Intersil manufacturer data sheet, it provides a full eight-bit bidirectional bus interface, an industry-standard 8286-compatible pinout, 20 mA B-side output-low drive capability, and an 8 mA input-high current specification. The DIR and output-enable inputs control bus direction and driver state.

Where can I download the CS82C86H datasheet PDF?

The CS82C86H manufacturer data sheet is available through the linked Intersil PDF archive and the all-datasheet document page. The original document identifies the device as a CMOS octal bus transceiver and covers its architecture, electrical characteristics, and 20-lead package information. Use the manufacturer document for design work because later distributor summaries can omit timing limits, recommended operating conditions, and individual pin descriptions.

Where can I find the CS82C86H pinout?

The CS82C86H uses the 20-lead PLCC pin arrangement documented for the Intersil CS82C86H, including eight A-side data pins, eight B-side data pins, DIR, OE, ground, and supply connections. The device is described as industry-standard 8286 compatible. Because PLCC packages are not universally keyed, verify the physical orientation mark and compare every numbered lead against the original data sheet before removing a board component.

What are the key specifications of CS82C86H that engineers should know?

The principal CS82C86H specifications are an 8-bit bidirectional data interface, a 4.5 V to 5.5 V supply range, 20 mA B-side output-low current, 8 mA input-high current, and a PLCC-20 package measuring 9 mm by 9 mm. According to the Intersil data sheet, the implementation uses a self-aligned silicon-gate CMOS process called Scaled SAJI IV. Propagation delay and operating-temperature limits should be read from the manufacturer data sheet before timing analysis.

What can replace the CS82C86H?

The closest documented replacement path is an 8286-compatible octal transceiver with the same PLCC-20 footprint, DIR and OE functions, and comparable 4.5 V to 5.5 V operation. A candidate must also match propagation delay, output-current behavior, setup and hold timing, and power requirements. The available cross-reference results identify the 8286-compatible family but do not establish a qualified pin-to-pin substitute, so verify the original data sheet before approving a replacement.

Is the CS82C86H the same as an 82C86H?

The CS82C86H belongs to the 82C86 family and implements the industry-standard 8286-compatible pinout described in the Intersil data sheet. However, the CS prefix and H suffix can identify a specific manufacturer, grade, package, or qualification context, so the abbreviated 82C86H name is not sufficient for a drop-in conclusion. Confirm package, pin numbering, supply voltage, timing, and lifecycle status on the exact replacement device.

What is the best equivalent for CS82C86H in a legacy bus design?

No cross-brand equivalent is established as a drop-in replacement by the available technical records. The defensible selection route is to search for an 8286-compatible octal transceiver in the identical PLCC-20 footprint, then compare DIR, OE, propagation delay, setup and hold timing, and output-current limits against the Intersil data sheet. This avoids treating a merely similar bus transceiver or a different package as a board-level replacement.

When should I choose the CS82C86H over another 82C86-family device?

Choose the CS82C86H when an existing design specifically requires its 8-bit bidirectional interface, 4.5 V to 5.5 V supply range, 8286-compatible arrangement, and PLCC-20 package. Select another family member only after checking its exact suffix, package, speed grade, temperature range, and lifecycle status. The CS82C86H is most appropriate when preserving an established board and its documented control conventions is more important than changing package or bus timing.

Is the CS82C86H suitable for bidirectional processor bus interfacing?

The CS82C86H is suitable for bidirectional processor and peripheral bus interfacing when the system can manage DIR and OE correctly. Its eight bidirectional data lines, 4.5 V to 5.5 V operating range, and 20 mA B-side sink-current specification support conventional 5 V CMOS bus signaling. The design must also provide valid control states at reset, suitable bus termination, and adequate setup and hold timing for the selected operating conditions.

How do DIR and OE control the CS82C86H?

DIR determines the direction of data transfer, while OE determines whether the output drivers are enabled. The manufacturer data sheet describes a full eight-bit bidirectional interface, meaning all eight data lines reverse direction together rather than operating independently. Firmware and hardware should hold the transceiver disabled during reset and whenever multiple devices could otherwise drive the same bus, preventing output contention.

How much current can the CS82C86H drive?

The documented CS82C86H output specification includes 20 mA on the B side and an 8 mA input-high current. These values describe specific test conditions rather than a blanket current rating for every bus load. The exact output-high and output-low voltage limits, timing conditions, and load configuration should be taken from the Intersil data sheet when checking whether a particular termination scheme remains within specification.

What layout precautions apply to a CS82C86H bus interface?

Keep the transceiver adjacent to the connector or bus driver it serves, and place pull-up or pull-down components where they can maintain the required idle level without creating long stubs. Route DIR and OE as control signals that cannot switch into an active-drive state during reset. Because the package is PLCC-20, confirm lead orientation, solderability, thermal cycling, and the board's available component clearance before production release.

Where can I buy the CS82C86H online?

The CS82C86H can be requested through the Request a Quote form on this page, where package, quantity, and production requirements can be reviewed before an order is placed. The product appears in current distributor search records, including a PLCC-20 listing, but the displayed starting-price summaries do not provide qualifying quantity-break data for this exact part. Request current availability, lead time, and a formal quotation for production planning.

What is the price of the CS82C86H?

Current pricing for the CS82C86H should be obtained through the Request a Quote form on this page. The listing records include a starting-price statement and a separate single-price reference, but neither provides a complete quantity-break schedule for the exact MPN and PLCC-20 configuration. Use the quote form to request the current unit price, order multiples, stock position, and lead time rather than relying on an introductory price.

What is the lead time for the CS82C86H?

The current CS82C86H lead time should be requested through the Request a Quote form on this page. Distributor search records show component listings, but they do not state a guaranteed lead time, production allocation, or lot-size schedule for the exact PLCC-20 device. Include your required quantity, target date, and approved-suffix status with the request so the quotation can reflect an executable supply plan.

Is the CS82C86H currently in stock?

The CS82C86H should be treated as quote-on-request until a current order confirmation is received through the Request a Quote form on this page. Search listings identify the component and describe stock in general terms, but no durable inventory guarantee is available for the exact MPN. Request confirmation of physical stock, date code, manufacturer origin, package condition, and production quantity before releasing a shipment plan.

انتخاب کی گائیڈ

Choose the CS82C86H when maintaining an established 5 V bidirectional byte bus is the primary objective, especially when the board expects the 8286-compatible arrangement in a PLCC-20 footprint. Its documented 4.5 V to 5.5 V supply range, eight bidirectional channels, DIR and OE controls, and 20 mA B-side sink-current specification align with conventional legacy CMOS bus designs. Select an 8286-compatible alternative only after confirming identical lead numbering, package dimensions, control polarity, timing, load capability, and lifecycle status. A different package may offer newer technology, but it requires PCB changes and qualification. For production continuity, treat the current quotation, manufacturer traceability, and exact suffix confirmation as mandatory procurement gates rather than relying on family-level similarity.

ڈیزائن نوٹس

Do not assume that an 8286-compatible pinout guarantees identical replacement behavior. Verify the exact package, lead numbering, DIR and OE polarity, propagation delay, setup and hold timing, and output-current limits before substituting another 82C86-family device. The CS82C86H is a PLCC-20 device, so a lead-compatible function in another package cannot be installed without changing the PCB footprint.

Place the transceiver near the connector or bus segment it serves, and keep DIR and OE traces short so reset or control glitches do not enable the drivers unexpectedly. Use pull-up or pull-down resistors only when the bus specification requires a defined idle level. Avoid long stubs from the main bus because they can create reflections that reduce the available timing margin.

Define DIR and OE states in hardware so the CS82C86H remains high impedance during reset, arbitration, and fault recovery. Check the complete network for multiple drivers, capacitive loading, and turnaround dead time before direction changes. The documented 20 mA B-side output-low current is a test-condition value, not a substitute for a board-level signal-integrity calculation.
