LT1132CN Présentation
An RS-232 transceiver is an interface IC that converts between digital logic-level signals and RS-232 line-level voltages. The LT1132CN combines transmitter and receiver functions in one package, reducing the number of interface components required in a serial port. In the broader electronics hierarchy, it belongs to interface ICs, line drivers and receivers, communication transceivers, and RS-232 interface devices. Its commercial-grade classification makes it relevant to equipment operating in ordinary commercial environments, although detailed temperature limits were not present in the supplied data.
The verified listing identifies the LT1132CN as a LINE TRANSCEIVER and supplies the package basics: 24 terminals, DIP package code, rectangular package shape, and through-hole terminal form. The supplied search results also associate the LT1132 family with low-power 5 V RS-232 drivers and receivers, but exact voltage, current, propagation-delay, driver-strength, receiver-threshold, and logic-level values are not provided. Those parameters should be confirmed in the manufacturer datasheet before final circuit design.
The transceiver can be used to connect a host controller to an RS-232 data link, especially where a compact, multi-function interface is preferred over separate driver and receiver ICs. Because this is a through-hole DIP device, it is well suited to through-hole prototypes, legacy equipment, repair applications, and industrial controller boards where a large package and socketed assembly are acceptable. The DIP outline also simplifies inspection and replacement, but it requires more board area than a surface-mount equivalent.
A key design consideration is that RS-232 uses voltage levels and signal polarity that are not directly compatible with ordinary CMOS or TTL logic. The transceiver handles that conversion, but the system still needs correct decoupling, grounding, connector protection, cable-length planning, and appropriate handling of unused enable or control pins. Because the supplied data does not specify exact pin names or all electrical limits, the LT1132CN pinout should be taken from the official datasheet rather than inferred from the package outline.
This page consolidates the verified distributor and manufacturer-related links for the LT1132CN, identifies the confirmed commercial DIP package information, and separates verified facts from parameters that still require datasheet confirmation. It also records the absence of verified pricing, lifecycle, compliance, pin-level, and direct drop-in replacement data to avoid presenting unsupported engineering assumptions.

Applications typiques
LT1132CN convient pour 6 applications: Computer Serial-Port Interface, Industrial Control Communication, Data-Acquisition Equipment, Embedded Controller Communication, Legacy Equipment Retrofit, Instrument and Test-System Communication.
Computer Serial-Port Interface
The LT1132CN is a natural fit for a legacy or industrial RS-232 data port because it is identified as a line transceiver and uses a conventional 24-pin through-hole DIP package. Place it between the host logic interface and the external DB9 or equivalent RS-232 connector, observing the device’s verified supply and grounding requirements. The DIP format makes retrofit and prototype work straightforward. Before layout release, confirm the exact pinout, logic-level compatibility, receiver thresholds, and driver limits from the manufacturer datasheet.
Recommandé
Industrial Control Communication
Use the LT1132CN in a controller board that needs a wired RS-232 link to a service terminal, programming fixture, or remote control unit. Its verified commercial-grade classification and through-hole DIP format support conventional industrial prototype and maintenance designs. The transceiver should be positioned near the connector, with a deliberate ground strategy and protection network for the exposed cable interface. Verify cable length, data rate, and electrical thresholds against the datasheet because those details are [DATA_NEEDED].
Recommandé
Data-Acquisition Equipment
The LT1132CN can serve as the serial communication interface for a laboratory instrument or data-acquisition unit that uses an RS-232 control and command port. The 24-pin DIP package is practical for through-hole instrument construction and socket-based service arrangements. Keep the transceiver’s supply decoupling close to its pins and route the connector-side interface away from sensitive analog sections. Since the supplied data does not state data rate, receiver threshold, or supply limits, confirm those parameters before selecting the device for a particular acquisition controller.
Recommandé
Embedded Controller Communication
For an embedded controller or service board, the LT1132CN can provide a wired RS-232 communication path between a host processor and external equipment. The through-hole package is suitable when a product revision uses a conventional DIP footprint and when board space is not tightly constrained. The interface design must account for logic-level translation between the controller and transceiver, power sequencing, and connector protection. Confirm the exact controller family and pin mapping rather than assuming compatibility with any specific site-listed MCU.
Recommandé
Legacy Equipment Retrofit
The LT1132CN is suitable for evaluating in retrofit boards that must preserve an older RS-232 connection while replacing or repairing surrounding logic. Its 24-pin DIP format allows socketed assembly, inspection, and replacement with a conventional through-hole layout. The retrofit should preserve the original signal naming only after checking the exact LT1132CN pinout and verifying that the original circuit’s supply and interface levels match. Use a transition or adapter board when the installed package footprint or connector arrangement differs.
Recommandé
Instrument and Test-System Communication
The LT1132CN can be evaluated in test and measurement equipment that uses RS-232 for command exchange, calibration data, or diagnostic output. The commercial-grade DIP package favors serviceable through-hole instrument designs, while the transceiver function consolidates interface circuitry. Place the device to minimize digital return currents and provide connector-side surge protection for cables entering the enclosure. Because the supplied verified data does not provide noise, timing, or temperature specifications, do not claim performance margins beyond the confirmed package and product category.

Notes de conception
Use the manufacturer datasheet to confirm the LT1132CN supply voltage, quiescent current, driver-load limits, and capacitor requirements before adding the device to a power rail. Place the specified supply and bypass capacitors close to the corresponding pins, and keep the transceiver’s ground return compact. Because the supplied verified material does not include electrical limits, capacitor values and rail tolerances must not be inferred from generic RS-232 designs.
The confirmed 24-pin DIP package is a through-hole device. Reserve the full pin-1-to-pin-24 footprint, maintain adequate spacing for the connector and cable entry, and provide clean routing from the transceiver to the external connector. If the board is already assembled with a surface-mount RS-232 IC, do not treat the package as interchangeable; use a footprint transition or a formally verified pin-compatible alternative.
Do not assign LT1132CN pins from the 24-pin DIP outline alone. Verify the exact datasheet pinout, power pins, driver inputs, receiver outputs, shutdown or enable functions, and exposed no-connect positions before layout or firmware integration. Also avoid assuming that every RS-232 transceiver is a drop-in replacement: channel count, logic levels, supply voltage, timing, and package assignments can differ even when the connector standard is the same.
Informations de conformité
The supplied verified data identifies commercial temperature grade but does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations.
