MC145028P - 9-Line CMOS Remote Control Decoder | NXP
N.º da peça: MC145028P ✗ Fim de vidaMC145028P Visão geral
A remote-control decoder is a logic IC that translates a serial communication stream into usable control signals. The MC145026, MC145027, and MC145028 devices form encoder/decoder families for remote-control applications. In such a hierarchy, an encoder converts parallel command information into a serial waveform, while a decoder receives that waveform, validates the address information, and reconstructs the data. The MC145028P is therefore a semiconductor interface and logic device rather than a general-purpose microcontroller or analog receiver.
The MC145028P supports nine encoded information lines, as described for the MC145026/27/28 encoder-and-decoder family. Its CMOS construction supports low-power remote-control system implementations, while the 16-pin DIP package facilitates through-hole assembly, prototyping, repair, and legacy industrial equipment. The identified package is a 0.300-inch, 7.62 mm 16-DIP configuration. Operating details beyond the package and basic device function require confirmation from the manufacturer datasheet.
The decoder is intended to work with a compatible remote-control transmitter, commonly an MC145026 encoder. The transmitter serializes address and command information when its transmit-enable signal is asserted. The receiver reconstructs the transmitted information and indicates whether the received command corresponds to the selected address. This arrangement allows one receiver system to respond selectively to one transmitter or group of transmitters.
Typical uses include industrial remote-control panels, access and equipment-control systems, telemetry links, model or process-control interfaces, and legacy embedded systems. The 16-DIP format is especially useful where a through-hole replacement is required, but board area and manual insertion limitations make the device less suitable for compact new portable products.
When designing around the MC145028P, match the encoder waveform, address coding, timing, and interface voltage levels rather than selecting the receiver from package appearance alone. Confirm the complete pin assignment and electrical limits in the manufacturer datasheet before routing a new PCB. This page combines device identity, package information, sourcing guidance, application fit, and design cautions for engineers evaluating legacy or repair applications.

Aplicações típicas
MC145028P é adequado para 6 aplicaçãos: Industrial Remote-Control Panels, Wireless Equipment-Control Receivers, Access and Security Control Heads, Telemetry Command Interfaces, Legacy Equipment Repair and Replacement, Model and Process Control Interfaces.
Industrial Remote-Control Panels
The MC145028P fits legacy industrial control panels that use an encoder and receiver pair for address-selective commands. Its CMOS decoder function reconstructs serially transmitted address and command information, while the 16-DIP package simplifies replacement in hand-assembled or through-hole controller boards. The designer should use the MC145026/27/28 timing and pin tables to define the encoder interface, verify supply limits, and confirm that the valid-data output matches the controller firmware. Its principal benefit is serviceability in established equipment rather than compactness or modern mixed-signal features.
Recomendado
Wireless Equipment-Control Receivers
MC145028P can serve as the command-decoding stage in a wireless equipment-control receiver built around a compatible RF or ultrasonic receiver stage. After the carrier is recovered and the encoded waveform is presented to the logic input, the decoder checks the transmitted address information and makes the decoded command available to the controller. The 16-DIP package is useful for prototype and repair hardware, but new compact products normally favor a surface-mount decoder. Exact input thresholds, timing margins, and logic levels must be checked against the encoder and receiver interface.
Recomendado
Access and Security Control Heads
The MC145028P is appropriate for address-selective access-control heads where a transmitter sends an encoded command and the receiver must distinguish an authorized address before acting. Its dedicated decoder role removes the need for the host controller to reproduce the complete remote-control encoding algorithm. A practical implementation requires secure address coding, suitable fail-safe behavior for an invalid command, and verification of the manufacturer’s valid-data timing. The through-hole DIP format helps maintain older access equipment, although security certification and modern threat requirements may justify a redesign.
Recomendado
Telemetry Command Interfaces
MC145028P can be used in telemetry equipment that accepts a compact command stream from a remote transmitter. The encoder-side device serializes up to the family’s nine information lines, and the MC145028P reconstructs the selected command for downstream control logic. This can simplify firmware in an established telemetry design because command decoding is handled by dedicated logic. Design validation should include worst-case timing margin, power-consumption review, and confirmation of signal levels between the receiver front end, decoder, and downstream controller.
Recomendado
Legacy Equipment Repair and Replacement
The MC145028P is especially useful for repairing legacy equipment that uses a through-hole 16-DIP remote-control decoder. The industrial-grade identification and familiar package can support direct board-level maintenance when the installed encoder waveform and terminal functions match the manufacturer documentation. Before ordering, inspect the device marking and confirm that the replacement requirement is for the decoder rather than the companion encoder. A successful repair also requires pin-by-pin orientation checks and validation of the supply rail before exchanging the IC.
Recomendado
Model and Process Control Interfaces
MC145028P can decode command information in model-control, test-equipment, and small process-control interfaces where a wired command transmitter communicates with a remote receiver. Dedicated decoding frees the main controller from handling the encoder waveform directly and supports address-selective responses. The device is most attractive when compatibility with an installed MC145026-family transmitter is mandatory. New designs should compare the MC145028P’s supply, timing, and package limits with current surface-mount decoders, particularly when reliability, board area, and automated assembly are priorities.

Notas de projeto
Do not select a replacement by pin count or package alone. The MC145028P must match the transmitter’s encoding scheme, address format, timing, and electrical levels. Confirm that the required device is the decoder rather than the companion encoder, then verify every terminal against the manufacturer pin-description table. A 16-pin remote-control IC with different logic functions can fit the same PCB outline electrically but fail at the protocol level.
Allow for the body width and lead geometry of the 0.300-inch, 7.62 mm 16-DIP package when creating a replacement footprint. Keep the DIP orientation unambiguous on the board because a reversed installation can place power and signal pins incorrectly. For new compact products, compare the mechanical cost of this through-hole format with a surface-mount decoder before committing the layout. Prototype boards should use sockets when repeated service is expected.
Validate the complete receiver chain with the actual encoder waveform rather than testing only static logic states. Check command timing margins, input thresholds, valid-data delay, and behavior during address transitions using the manufacturer timing diagrams. Account for the receiver front end’s noise and distortion when it drives the decoder input. Keep the decoded control path physically separated from noisy switching nodes to reduce false commands.
