概述

Description

Introduction to TSSP77038TR
- Type: 38 kHz infrared remote-control receiver with integrated demodulator (TSSP family from Vishay).
- Function: Converts modulated IR signals from remote controls into a clean digital data stream for a microcontroller.
- Internals: Built-in preamplifier, automatic gain control, 38 kHz band-pass filter, and demodulator.
- Output: Three-pin device (GND, VCC, OUT); CMOS/TTL-compatible logic output.
- Power: Operates from 2.7–5.5 V; consumption is in the low mA range.
- Packaging: TR indicates Tape-and-Reel packaging (for automated assembly).
- Applications: Common in TVs, set-top boxes, audio/video gear, and other IR remote receivers.
- How to use: Power the device, connect OUT to a microcontroller input (with pull-up if needed), and decode the resulting data stream with a standard IR protocol (NEC, RC5, etc.).

Features

Here are the key features of TSSP77038TR (infrared receiver):
- 38 kHz IR remote receiver with integrated preamplifier, AGC, and 38 kHz band-pass filter
- Demodulated, TTL/CMOS-compatible data output (active low)
- 3-pin package: Vcc, GND, OUT
- High ambient-light and EMI immunity; built-in noise rejection
- Low external components; direct to microcontroller
- Wide operating voltage: typical 2.7–5.5 V
- Low supply current (typical in the 1–2 mA range)
- Suitable for standard IR remote protocols; outputs a clean data stream
- Tape & Reel (TR) packaging for automated assembly
Note: Verify exact electrical specs in the latest datasheet for your application conditions.

Package

TR indicates Tape‑and‑Reel packaging. The TSSP77038TR is a 3‑pin surface‑mount IR receiver in a molded SMD package.

Pinout

- Pin count: 3 pins
- Function: 38 kHz infrared remote control receiver (with built-in preamp, AGC, and demodulator) that outputs a digital data signal. Pins are Vcc, GND, and OUT.

Manufacturer

- Manufacturer: Vishay Intertechnology (Vishay Semiconductors).
