Description
TSOP6438TT is a 38 kHz infrared receiver module from Vishay for remote-control systems. It integrates the IR photodiode, preamplifier, automatic gain control, 38 kHz band-pass filter, and a demodulator with a clean digital output.
Key points:
- Supply: 4.5–5.5 V; typical current of a few milliamps.
- Output: TTL/CMOS logic, active low (idle high); no external demodulation needed.
- Range/protocols: works with standard 38 kHz remotes and common protocols (NEC, RC5/RC6, Sony SIRC); requires line-of-sight.
- Pinout: Vcc, GND, OUT (3-pin package); TSOP6438TT often supplied in Tape & Reel.
- Use: ideal for TVs, set-top boxes, audio gear; include a nearby decoupling capacitor (e.g., 0.1 µF).
Notes: sensitive to ambient light and alignment; detects only modulated 38 kHz IR signals.

Equivalent
TSOP6438TT is a 38 kHz IR remote control demodulator (3-pin). Equivalents (same function/pinout) include Vishay TSOP1738, TSOP1838 and TSOP4838. Other vendors’ 3-pin 38 kHz IR receivers (e.g., VS1838B modules) can be used as substitutes, provided voltage, timing, and output logic match your design.
Features
Key features of TSOP6438TT (38 kHz IR receiver):
- 38 kHz remote-control IR receiver with demodulated output
- Integrated preamplifier, automatic gain control (AGC), and input filtering
- Demodulated, active-low TTL/CMOS-compatible output
- Wide supply range: typically 4.5–5.5 V
- Low standby current and overall low power consumption
- Robust ambient-light rejection and narrow-band IR filter
- Suitable for most 38 kHz protocols (e.g., NEC, RC5/RC6, Sony SIRC)
- Small, 3-pin package (Vcc, GND, Out) suitable for compact electronics
- No external components required for basic operation
Note: exact packaging suffix (TT) denotes packaging/lot type; electrical behavior remains as described.
