ISL8563IB - 250kbps RS-232/RS-562 Transceiver | Renesas Electronics
MPN: ISL8563IB ✗ Cuối đờiISL8563IB Tóm tắt
An RS-232 transceiver is an interface IC that combines voltage-level transmitters and receivers for unbalanced serial communication. It belongs to the driver, receiver, and transceiver hierarchy within interface ICs, converting logic-level signals into RS-232-compatible levels and reconstructing received logic signals. The RS-562 standard is referenced alongside EIA/TIA-232 and EIA/TIA-562, allowing the ISL8563 family to support both communication approaches where compatible with the system interface requirements.
The ISL8563IB provides two transmit channels and two receive channels, supporting a complete dual-direction serial interface in one package. Its maximum data rate of 250kbps accommodates higher-speed legacy serial links, while the 3V to 5.5V supply range supports both 3V and 5V system rails. The approximately 1µA operating-current figure is particularly relevant to portable equipment where standby and overall battery consumption constrain the usable architecture.
ESD protection of ±15kV strengthens the device against electrostatic discharge encountered during connector handling and field use. The 18-pin SOIC package also provides a conventional surface-mount option for RS-232 ports. Because the available verification data does not include the complete electrical tables, exact output levels, slew rates, receiver thresholds, and internal charge-pump details, designers should consult the manufacturer datasheet before finalizing timing, capacitance, and signal-integrity margins.
Typical uses include serial ports in portable computers, PDAs, palmtop computers, digital cameras, battery-operated instruments, and other equipment requiring an RS-232 or RS-562 connection. In a portable design, the 3V-to-5.5V operating range permits connection to either rail, while the low 1µA operating-current characteristic supports power-conscious operation. Designers should still confirm whether the cited value applies to a specific mode or test condition in the datasheet.
The primary design consideration is preserving adequate driver, receiver, and connector margins under the actual cable and load conditions. Place the transceiver close to the interface connector, provide the required bypass capacitance, observe the maximum supply voltage of 5.5V, and validate the complete channel with the intended cable length and baud rate. The available data does not provide a verified pin-by-pin mapping, so the package drawing and pin descriptions should be taken directly from the manufacturer datasheet.
This product record consolidates the verified distributor specifications, package information, commercial availability, and practical selection considerations for the ISL8563IB. It also distinguishes verified facts from parameters that still require datasheet confirmation and explains why no unverified cross-brand substitute is presented as a guaranteed drop-in replacement.

Ứng dụng tiêu biểu
ISL8563IB phù hợp cho 6 Áp dụngs: Portable Computer Serial Port, PDA and Palmtop Connectivity, Digital Camera Serial Interface, Battery-Powered Instrumentation, Industrial RS-562 Link, Legacy Peripheral Data Port.
Portable Computer Serial Port
The ISL8563IB fits legacy serial-port designs in portable computers because it combines two transmit channels and two receive channels with operation from 3V to 5.5V. A 3V system can use the same 250kbps interface family without requiring a 5V-only transceiver, subject to the complete timing and output-level specifications. Its approximately 1µA operating-current figure is useful when power consumption matters, although the applicable test condition must be confirmed. The 18-pin SOIC package is especially practical for existing notebook and PDA layouts that already use the ISL8563 footprint. The board should place bypass and charge-pump capacitors close to their associated pins and route the connector-side driver outputs away from sensitive receiver inputs.

PDA and Palmtop Connectivity
The ISL8563IB is suitable for PDA and palmtop serial connectivity because its 3V-to-5.5V supply range accommodates low-voltage portable platforms while its two transmitters and two receivers support a practical RS-232 port arrangement. The verified 250kbps rate is sufficient for many legacy synchronization and peripheral connections, although the intended baud rate and cable must be checked. The approximately 1µA operating-current characteristic supports power-conscious designs, but designers should verify whether it applies to shutdown, load, or another specific condition. For a compact mixed-signal PDA board, keep the interface return path short and place protection components near the external connector.

Digital Camera Serial Interface
The ISL8563IB can support a legacy serial-control connection in a digital camera when the host requires an RS-232 or RS-562-compatible interface. Its two transmitters and two receivers provide flexibility for command and response paths, while operation down to 3V suits portable imaging equipment powered from a limited rail. The 250kbps maximum rate is relevant when validating camera-controller timing, and ±15kV ESD protection adds useful connector-facing robustness. Nevertheless, cable length, connector pinout, logic levels, and camera-specific timing must be confirmed in the system specification. A low-ESR bypass capacitor and a short ground return are recommended because long external cables can couple transient noise into the receiver path.

Battery-Powered Instrumentation
The ISL8563IB is appropriate for battery-powered instrumentation that needs a conventional RS-232 or RS-562 service port. Its 3V-to-5.5V operating range allows operation from either a 3V system rail or a 5V rail, and the approximately 1µA operating-current figure can reduce the burden on a compact battery budget when the cited operating condition applies. The 250kbps capability supports instrument configuration and data-transfer links that exceed older low-speed serial limits. Engineers should verify supply current across operating modes, confirm the receiver’s behavior during disconnected-cable conditions, and account for ESD exposure at the user-accessible connector. Low-power states should be validated against the complete datasheet before being included in battery-life calculations.
Được đề xuất
Industrial RS-562 Link
The ISL8563IB can be used in an RS-562 point-to-point system when the interface specification requires EIA/TIA-562 behavior and a single-ended serial link. Its two transmitters and two receivers cover the usual transmit and receive functions, while the 250kbps rating provides a useful margin for many legacy control links. The 3V-to-5.5V supply range allows the same device to be used across industrial and embedded control systems with different rail voltages. Engineers must confirm line-driver loading, receiver thresholds, cable capacitance, and grounding because those details are not available in the supplied excerpts. The device should be placed close to the connector, with protection and filtering selected according to the actual cable environment.
Được đề xuất
Legacy Peripheral Data Port
The ISL8563IB supports legacy peripheral data ports that use RS-232 or RS-562 signaling, including equipment intended to interoperate with older host systems. A data rate of up to 250kbps provides flexibility for moderate-speed command and diagnostic links, and the two transmitters and two receivers allow both directions to be integrated in one package. The 18-pin SOIC format supports surface-mount production, but it is larger than several modern alternatives, so board-area and assembly requirements should be checked before new adoption. The 3V-to-5.5V operating range can simplify mixed-voltage interfaces, while ±15kV ESD protection is beneficial near an external connector. Confirm the exact board pinout and charge-pump requirements from the manufacturer datasheet before schematic capture.

Ghi chú thiết kế
Verify the supply decoupling and voltage limits directly against the Intersil manufacturer datasheet. The verified operating range is 3V to 5.5V, so the ISL8563IB must not be operated above 5.5V. Place the required bypass capacitor close to the power and ground pins, and confirm the charge-pump capacitor values and layout because the supplied excerpts do not include those values.
Keep the RS-232 driver outputs and connector interface as short as practical, while maintaining separation from sensitive receiver inputs and low-level analog circuitry. Confirm the exact package orientation and pin functions from the manufacturer datasheet before PCB release because the available verification data confirms an 18-pin SOIC but does not provide a verified pin-by-pin mapping.
Do not treat an RS-232 or RS-562 transceiver as interchangeable with an RS-485 device. The signaling levels, grounding, topology, and cable behavior differ, even when two transmitters and two receivers are present. Also verify the intended baud rate against the verified 250kbps maximum and account for connector capacitance, cable length, and external protection components.
