MAX232ACPE+ - RS-232 Transceiver, 5V, PDIP-16 | Maxim
MPN: MAX232ACPE+ ✗ Cuối đờiMAX232ACPE+ Tóm tắt
An RS-232 transceiver is an interface IC that translates digital logic levels between a host or controller and a RS-232 cable. A driver converts TTL or CMOS signals into RS-232-level signals, while a receiver converts transmitted RS-232 levels back into logic levels. The MAX232ACPE+ is therefore placed between a digital system and an external serial connector, providing bidirectional communication through two driver and two receiver channels.
The manufacturer family description states that the MAX220–MAX249 devices are intended for EIA/TIA-232E and V.28/V.24 communications interfaces, particularly where ±12 V is not available. The +5 V-powered architecture supports systems whose logic supply is commonly 5 V. The verified data also identifies the part as a 2/2 transceiver and as a 5 V multichannel RS-232 driver/receiver. Exact electrical limits, slew rates, receiver thresholds, supply-current figures, and temperature limits are marked as DATA_NEEDED because they are not included in the supplied verified excerpts.
Typical uses include RS-232 console links, industrial-control serial ports, test equipment, embedded serial adapters, and legacy peripheral connections. The MAX232ACPE+ is appropriate when the board requires a conventional through-hole RS-232 interface and a 16-pin PDIP footprint. Designers should verify the complete datasheet pinout, charge-pump capacitor requirements, logic levels, data-rate limits, and ESD requirements before production release, because those values are not present in the supplied source snippets.
The key design consideration is to treat the MAX232ACPE+ as a physical-layer interface rather than a protocol converter. The application must handle framing, baud-rate configuration, parity, flow control, and connector wiring separately. External charge-pump capacitors, input/output protection, grounding, and cable routing remain important in a working RS-232 design. The MAX232ACPE+ is best selected when a 16-pin PDIP RS-232 transceiver with two drivers and two receivers is required and the existing board already matches the verified package and pin arrangement.

Ứng dụng tiêu biểu
MAX232ACPE+ phù hợp cho 6 Áp dụngs: RS-232 Console Interface, Industrial Control Serial Port, Test and Measurement Equipment, Embedded Serial Adapter, Legacy Peripheral Connectivity, Battery-Powered RS-232 Equipment.
RS-232 Console Interface
MAX232ACPE+ fits a console connection between a 5 V controller and an RS-232 terminal because it provides two driver channels and two receiver channels in a 16-pin PDIP package. The MAX220–MAX249 family is intended for EIA/TIA-232E and V.28/V.24 interfaces where ±12 V is unavailable. Place the transceiver between the controller UART and the connector, then use the device’s charge-pump network and logic-side supply exactly as specified by the manufacturer datasheet. The supplied sources verify the 2/2 channel count and +5 V-powered concept, but exact logic thresholds, data rate, and capacitor values remain DATA_NEEDED.
Được đề xuất
Industrial Control Serial Port
The MAX232ACPE+ can provide a conventional RS-232 physical layer for industrial equipment that retains a 5 V logic supply and uses a through-hole interface IC. Its two transmitters and two receivers support multiple RS-232 signal paths, while the family description confirms suitability for V.28 and V.24-style communications. The circuit must still handle protocol timing, connector pin assignment, cable return, and protection. Verify the complete PDIP pinout and operating-temperature limits because those details are not included in the supplied excerpts.
Được đề xuất
Test and Measurement Equipment
A MAX232ACPE+ is appropriate for legacy test equipment that exposes a 5 V RS-232 service port. The transceiver bridges the instrument’s digital control logic and an external PC or controller without requiring separate ±12 V supplies, which the verified MAX220–MAX249 description specifically highlights. Use the driver outputs toward the RS-232 connector and receiver inputs toward the instrument logic. Because the supplied sources do not state data rate, ESD level, receiver threshold, or charge-pump capacitor recommendations, those values must be validated before layout signoff.
Được đề xuất
Embedded Serial Adapter
MAX232ACPE+ can terminate an older RS-232 link on an embedded controller board that uses 5 V digital logic and has a suitable PDIP footprint. The two-driver/two-receiver arrangement is useful when the system needs more than one serial signal, while the +5 V-powered family architecture simplifies systems without ±12 V rails. The board still needs connector protection, defined grounding, and verified charge-pump capacitors. Do not substitute a surface-mount alternative without confirming that the mechanical footprint and pin functions match.
Được đề xuất
Legacy Peripheral Connectivity
The MAX232ACPE+ is useful when a modern controller must communicate with a legacy peripheral through RS-232 rather than a modern differential bus. The MAX220–MAX249 family description specifically targets EIA/TIA-232E and V.28/V.24 interfaces, and the verified listing confirms two transmit and two receive channels. Designers should implement the UART protocol and connector wiring separately from the transceiver’s physical-layer function. Confirm the exact MAX232ACPE+ pinout, temperature grade, and external capacitor requirements before release.
Được đề xuất
Battery-Powered RS-232 Equipment
The MAX220–MAX249 family description highlights applications where ±12 V is unavailable, making MAX232ACPE+ a candidate for battery-powered or single-supply RS-232 equipment. The +5 V-powered transceiver can sit between a low-voltage digital subsystem and an RS-232 port, avoiding a separate dual-rail driver supply. Actual battery suitability depends on supply-current limits, shutdown behavior, and standby consumption, none of which are included in the supplied data. Those values must be checked in the complete manufacturer datasheet before claiming low-power operation.

Ghi chú thiết kế
Because the verified package is a 16-pin PDIP, preserve through-hole footprint clearance and route the RS-232 connector, logic-side UART, and protection network around the transceiver. Confirm the exact pin assignment from the manufacturer datasheet before fabrication; the supplied excerpts do not provide a complete numbered pinout, so a generic MAX232 diagram should not be copied without verification.
Treat the MAX232ACPE+ as a +5 V RS-232 transceiver and decouple the supply close to the device using the manufacturer’s recommended capacitor network. The MAX220–MAX249 family uses charge-pump circuitry for single-supply RS-232 operation, but the exact external capacitor values and tolerances are DATA_NEEDED in the supplied data. Do not select capacitors from generic RS-232 examples without checking the exact datasheet.
Do not assume that MAX232ACPE+, MAX232EPE+, MAX232AC/D, MAX232ACUE+, or MAX232ACWE-T are automatically interchangeable. The supplied comparison data reports 200 kb/s versus 120 kb/s and 0 C versus -40 C for MAX232ACPE+ versus MAX232EPE+, while the other source excerpts explicitly require package and pinout checks. Validate suffix-specific ratings and the complete pinout before substitution.
Keep the RS-232 connector, cable entry, protection components, and transceiver interface path physically separated from sensitive analog or high-speed digital circuits. The transceiver handles the physical RS-232 levels, not cable shielding, grounding, or protocol framing. Validate return-path continuity and connector pin assignments in the system schematic and layout.
Thông tin tuân thủ
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. EIA/TIA-232E and V.28/V.24 are interface application references from the manufacturer-family description, not independent compliance certifications.
