ISL8563CP - 250kbps RS-232 Transceiver | Renesas
MPN： ISL8563CP ✓ 啟用中ISL8563CP 概覽
An RS-232 transceiver is an interface IC that converts logic-level transmit and receive signals into RS-232-compatible levels, then restores received RS-232 signals to logic levels for a host, controller, or peripheral. The ISL8563CP belongs to the interface IC category and combines two transmitters and two receivers in one package, providing bidirectional communication over two data channels.
Its documented headline characteristics include operation from +3 V to +5.5 V, 1 µA operating supply current, and a maximum data rate of 250 kbps. The indexed datasheet states that the transmitters and receivers meet EIA/TIA-232 and EIA/TIA-562 specifications even when the supply voltage is 3.0 V. These characteristics suit equipment where low voltage compatibility and reduced supply demand are important.
The ISL8563CP contains two complete transmit channels and two receive channels, allowing two simultaneous RS-232 links within one device. Unlike single-direction level-shifter blocks, this integrated arrangement reduces the component count required for a dual-port interface. Its 18-pin PDIP package is suitable for through-hole assembly and prototype or legacy system designs where a surface-mount package is unnecessary.
Typical uses include RS-232 ports for personal digital assistants, palmtop computers, notebook and laptop computers, industrial control equipment, diagnostic interfaces, and embedded data-logging systems. A board designer can place the transceiver between a host UART and an external DB9 or other RS-232 connector, while observing the interface voltage, grounding, and protection requirements of the RS-232 environment.
Designers should verify the logic levels, receiver thresholds, transmitter output levels, capacitance loading, and external protection requirements against the complete datasheet before production use. Because the verified results do not provide a complete pin table, exact pin names, temperature range, or recommended external network values, those details require confirmation from the original manufacturer documentation. The 1 µA operating-current figure should also be understood under its stated test conditions rather than assumed across every operating mode.
This page consolidates the verified distributor indexing, package information, interface standards, operating limits, and application guidance for the ISL8563CP. It also distinguishes confirmed technical facts from unavailable details and avoids presenting unverified drop-in equivalents or fabricated pricing as authoritative purchasing data.

典型應用
ISL8563CP 適用於 6 應用s: Portable Computer RS-232 Port, Embedded Data Logger, Industrial Diagnostic Interface, Battery-Powered Field Instrument, Configuration and Programming Port, Service Console Connection.
Portable Computer RS-232 Port
The ISL8563CP fits legacy portable equipment that requires an RS-232 interface from a +3 V to +5.5 V system rail. Its two transmitters and two receivers support two bidirectional data paths, while the verified 250 kbps rating accommodates conventional serial peripherals rather than high-speed differential links. The 18-pin PDIP package is useful for through-hole prototypes and legacy equipment, although current designs may prefer a smaller surface-mount transceiver. Designers should verify the UART logic levels, connector pin assignment, and protection components before use.
推薦
Embedded Data Logger
The ISL8563CP can provide dual RS-232 links between an embedded controller and external instrumentation. Its dual-transmitter, dual-receiver arrangement allows two communication paths in one package, and the +3 V to +5.5 V operating range supports both 3.3 V and 5 V embedded rails. The 250 kbps maximum rate is suitable for many logging and configuration protocols. Engineers should account for cable capacitance, grounding, ESD protection, and the unspecified receiver thresholds before finalizing the interface.
推薦
Industrial Diagnostic Interface
The ISL8563CP is appropriate for diagnostic equipment that communicates with legacy RS-232 service ports through a controller UART. Its 1 µA operating-current specification can help reduce demand in low-power service tools, while dual channels can support separate command and data links. The device operates from +3 V to +5.5 V and supports rates up to 250 kbps. Because industrial connectors can incur ESD and ground-potential hazards, the design should include appropriate protection and isolated or correctly referenced grounding where required.
推薦
Battery-Powered Field Instrument
The ISL8563CP can serve as the RS-232 interface in a battery-powered field instrument where a +3 V to +5.5 V rail and modest data rate are sufficient. Its indexed 1 µA operating current is attractive when the interface remains active, although the applicable test conditions must be confirmed. The 250 kbps capability is more than adequate for many sensor-configuration and status protocols. Board designers should measure the complete interface power budget and add connector protection without unnecessarily loading the low-power receiver path.
推薦
Configuration and Programming Port
The ISL8563CP can connect a controller to a legacy configuration or programming port while providing two transmit and two receive channels for multiplexed or separate links. Its 250 kbps maximum rate is well matched to many host serial protocols, and operation from 3.0 V is explicitly noted in the verified datasheet information. The 18-pin PDIP footprint also simplifies adaptation to older through-hole motherboard layouts. Before substitution or layout reuse, verify every pin against the complete original datasheet because the supplied results do not include the pin table.
推薦
Service Console Connection
The ISL8563CP is suited to service-console equipment that must connect to older RS-232 service ports using a 3.3 V or 5 V controller. Dual transmitters and receivers allow the interface to support more than one serial path without separate transceiver ICs, while the 250 kbps rate covers many console and firmware-update protocols. In service equipment, designers should prioritize verified logic thresholds, TX output swing, shutdown behavior, and connector protection. Those specifications are not fully exposed in the search snippets and must be checked in the manufacturer datasheet.

主要差異化特點
- Two bidirectional RS-232 channels in one device (對比MAX232DR)
- Compatibility with both 3.3 V and 5 V system rails (對比MAX232DR)
- Low-power operating specification (對比MAX232DR)
設計說明
Treat the indexed 1 µA operating-current figure as a specific test-condition value rather than a universal consumption number. The verified data does not expose the test conditions, load state, or operating mode. Review the original datasheet for active, unloaded, and disabled behavior before calculating a battery budget, and include the input and output transition currents of the connected UART and any external protection components.
The verified information identifies an 18-pin PDIP package but does not expose the complete pinout. Do not infer assignments from a generic RS-232 transceiver. Before PCB release, compare the original manufacturer pin table, place input and output grounds according to the recommended layout, and route the connector-side RS-232 nets away from sensitive low-level signals. Through-hole lead spacing and insertion clearance also require checking against the actual package drawing.
An RS-232 transceiver does not by itself provide complete electrical protection for an exposed connector. Add the appropriate surge, ESD, and line-driver network required by the target interface, and verify that protection components do not distort receiver thresholds or transmitter rise and fall times. Also confirm that the host logic voltage, UART polarity, baud rate, and RS-232 signal direction are compatible before assembly.
合規資訊
The Veswin Electronics search result explicitly describes the ISL8563CP as RoHS compliant. No verified REACH, halogen-free, conflict-minerals, or automotive qualification evidence was supplied; AEC-Q100 is not applicable because this is a general-purpose RS-232 interface IC.
