Key Features
- Remote control receiver IC decoding encoded serial data streams at supply voltages up to 18 V for flexible power rail integration
- 16-pin DIP package enabling rapid prototyping and through-hole assembly in development kits and legacy consumer products
- CMOS design providing low quiescent current in standby for always-on remote control reception in battery-backed systems
- Integrated encoder/decoder function reducing external component count in bidirectional remote control link designs
- Wide supply voltage range from logic-level 5 V through 18 V accommodating diverse consumer and industrial power rails
Applications
The M145027B1 is used in infrared remote control receiver modules for televisions, audio equipment, and home automation hubs where decoded address and command data must be extracted from encoded serial IR transmissions. Its wide 5 V to 18 V supply range allows integration into both battery-operated handheld remotes and mains-powered set-top receiver boards without external regulators. Legacy industrial panels and access-control systems also leverage this IC to decode proprietary RF or IR command sequences across short-range wireless links up to several meters.

Frequently Asked Questions
What supply voltage range does the M145027B1 operate across, and how does that affect its integration in 5 V and 12 V systems?
The M145027B1 operates from 5 V up to 18 V supply, making it directly compatible with both 5 V microcontroller-based systems and 12 V to 15 V consumer electronics power rails without intermediate regulation. This flexibility allows a single BOM to cover TV remote receiver boards running from a 9 V rail and industrial panel controllers powered from a 12 V SMPS.
How many address and data bits can the M145027B1 encode and decode for remote control command differentiation?
The M145027B1 encodes and decodes serial data words with multiple address and function bits as defined in the MC145026/27/28 protocol family, typically supporting 9 bits of address and function information per transmission. This provides up to 512 unique command codes, sufficient to uniquely address individual devices and differentiate dozens of button functions in a full-featured TV or audio remote control system.
What is the 16-pin DIP package footprint of the M145027B1, and does it suit modern SMT-only PCB production lines?
The 16-pin DIP package has a 0.6-inch (15.24 mm) row spacing and 0.1-inch (2.54 mm) pin pitch, occupying roughly 20 mm × 7 mm of PCB area. Through-hole DIP insertion requires wave-soldering or hand-assembly, making it less suitable for fully automated SMT reflow lines; designers transitioning to SMT should evaluate the equivalent SOIC-16 package alternative or add a DIP socket for rapid prototyping.
In which legacy and repair scenarios does sourcing the M145027B1 remain relevant despite its YTEOL status?
The M145027B1 remains relevant for field repair of older consumer AV equipment manufactured in the 1990s and early 2000s that used the MC145026/27/28 encoder-decoder family as their remote control front-end. Its 16-pin DIP form factor is also popular in electronics education labs and hobbyist IR remote projects at 5 V supply, where students use it to decode standard IR protocols without writing any software decoding routines.
