ISL8563CB - 2/2 RS-232 Transceiver, 250kbps | Renesas
Teilenummer: ISL8563CB ✗ AbgekündigtISL8563CB Übersicht
An RS-232 transceiver is an interface IC that converts logic-level signals between a host or controller and a RS-232 physical link. The transmitter converts low-voltage digital signals into RS-232-level voltages, while the receiver converts the bipolar RS-232 input back into a logic-compatible signal. Within the broader hierarchy, this device is a line-driver and receiver interface IC used to bridge digital systems with RS-232 equipment.
The ISL8563CB operates from a single +3 V to +5.5 V supply, including the lower-voltage condition identified in the verified datasheet description. Its low-power operation is specified at 1 microamp, making it relevant to portable and space-constrained systems where standby consumption matters. The guaranteed 250 kbps minimum data rate supports common serial-control, point-of-sale, industrial-interface, and legacy peripheral connections without requiring a separate high-speed transceiver.
The device requires only four external 0.1 microfarad capacitors according to the verified manufacturer-datasheet description. This small external-component count simplifies layout and reduces the number of placement and routing decisions around the interface. Because the ISL8563CB integrates two transmitters and two receivers, each channel direction can be implemented without duplicating the driver or receiver function in separate packages.
Typical uses include RS-232 links in personal digital assistants, palmtop computers, notebook and laptop computers, embedded control systems, and industrial data-acquisition equipment. The same device can also support service-console, configuration-port, and point-of-sale interfaces where an EIA/TIA-232-compatible physical layer is required but board area and standby power are constrained.
Designers should verify signal levels, grounding, cable length, and system requirements against the manufacturer datasheet before replacing a discrete RS-232 implementation. The four external 0.1 microfarad capacitors should be placed close to their associated device pins, while supply and ground planes should provide a low-impedance return path. Because the verified data does not provide a complete 18-pin mapping, the package drawing and pin definitions must be checked against the datasheet before PCB release.
This page consolidates the verified supply, speed, power, package, standard-compliance, pricing, and sourcing information for ISL8563CB and adds practical application guidance. It also explicitly distinguishes verified facts from parameters that remain unavailable in the supplied data, including detailed pin definitions, temperature limits, and confirmed drop-in substitute MPNs.

Portable Computer Serial Interface
The ISL8563CB fits portable and legacy-computing systems that require an RS-232 port with limited standby power and a compact footprint. Its 2/2 organization provides two transmitters and two receivers on one 18-pin SOIC device, while the verified 1 microamp operating figure supports low-power design goals. A single 3 V to 5.5 V supply simplifies system integration, and the guaranteed 250 kbps data rate covers conventional serial-control traffic. The four required 0.1 microfarad capacitors should be placed adjacent to the associated pins, while the shared ground return must preserve the integrity of both receive and transmit channels.

Point-of-Sale Terminal Connectivity
The ISL8563CB is suitable for point-of-sale equipment that connects a controller or peripheral through an EIA/TIA-232-compatible link. Two integrated transmitters and two receivers allow multiple channel directions without requiring separate driver and receiver packages, reducing board-area demand. Its 250 kbps minimum guaranteed data rate is appropriate for transaction traffic, configuration commands, and service data. The device accepts a supply between 3 V and 5.5 V, which permits use in systems using either common logic-rail range. Designers should place the four 0.1 microfarad capacitors close to the IC, route driver outputs away from sensitive receiver inputs, and verify ground-return requirements against the manufacturer application guidance.

Industrial Data Acquisition
The ISL8563CB can provide a compact RS-232 connection in industrial data-acquisition and control equipment. The integrated 2/2 transceiver arrangement supports multiple command and status channels while requiring only four external 0.1 microfarad capacitors according to the verified datasheet description. Operation from a single 3 V to 5.5 V supply allows the interface to be placed beside 3.3 V or 5 V control electronics. The guaranteed 250 kbps rate is suitable for many configuration and telemetry functions that do not require continuous high-bandwidth transfer. For reliable operation, the layout should minimize return-path impedance, maintain adequate spacing between transmit and receive routes, and include the interface protections required by the target installation environment.
Empfohlen
Embedded Configuration Port
The ISL8563CB is appropriate for an embedded controller that needs a legacy configuration or maintenance port. Two receivers can accept commands or status from two sources, and two transmitters can return responses on two channels, subject to the manufacturer's pin and operating requirements. The 18-pin SOIC package provides a comparatively compact implementation, while the four 0.1 microfarad external capacitors keep the support network simple. The 3 V to 5.5 V supply range supports common embedded rails, and the 250 kbps minimum rate is more than sufficient for many textual configuration protocols. Engineers should confirm the supported data format and idle-state behavior in software and ensure the port connector's electrical protection does not distort the receiver thresholds.

Personal Digital Assistant Connectivity
The ISL8563CB directly matches the portable-device use cases identified in the verified device description, including PDAs and palmtop computers. Its 2/2 full-duplex transceiver organization allows a compact system to implement several RS-232 channels, while 1 microamp low-power operation is valuable in battery-oriented equipment. The device can run from a 3 V to 5.5 V supply and guarantees at least 250 kbps, making it suitable for short, burst-oriented serial exchanges. The low external-capacitor count preserves board area in portable designs. Layout must still prioritize short capacitor connections, controlled ground return, and separation between transmit and receive paths to avoid coupling noise into the low-level receiver inputs.

RS-232 to Logic Level Bridging
The ISL8563CB can bridge a host UART or logic controller to external RS-232 equipment by converting logic-level signals into RS-232 levels and converting received RS-232 signals back to logic-compatible levels. Its integrated two transmitters and two receivers reduce component count compared with a design using separate driver and receiver ICs. The 250 kbps minimum data rate supports many control, diagnostic, and legacy peripheral links, and the single 3 V to 5.5 V supply simplifies rail planning. Board layout should keep the four 0.1 microfarad capacitors close to the device, provide a continuous ground reference, and route the relatively high-voltage transmit nets separately from sensitive receive nets to minimize crosstalk and ground-bounce effects.

- Low documented operating current (vs. SP232ECT-L)
Designhinweise
Place the four required 0.1 microfarad capacitors as close as practical to the ISL8563CB pins identified by the manufacturer datasheet. Keep the traces short, provide a direct ground return, and avoid sharing narrow return paths between transmit and receive channels. The verified datasheet description identifies the four-capacitor network, but the supplied material does not include the complete pin map, so the final placement must be checked against the official application circuit.
Route the two RS-232 transmit paths away from the two receiver inputs and from sensitive control or analog signals. Transmitter outputs swing to RS-232 voltage levels and can couple into adjacent low-level receive traces when routing or grounding is poor. Where the layout permits, use a solid ground plane, short receiver routes, and a symmetrical arrangement of the two transmit and two receive channels.
Do not treat the ISL8563CB's 2/2 designation as permission to connect interfaces without checking polarity, signal direction, and connector pin assignment. Confirm the exact 18-pin SOIC mapping from the manufacturer datasheet because that information is absent from the supplied snippets. Also verify that the host voltage levels, grounding method, cable length, and connector protection are appropriate for the target EIA/TIA-232 or EIA/TIA-562 system.
Compliance-Informationen
The verified material confirms EIA/TIA-562 and EIA/TIA-232 interface compliance but does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is treated as not applicable because no automotive qualification is stated.
