This release in:

MALVERN, Pa. — November 29, 2006 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced the addition of four new modules featuring superior performance for pulse-distance coding to its TSOP1xxxx series of IR receivers.

Designed to address the class of coding protocols using pulse-to-pulse or simply presence of pulse timing methods, the new TSOP18238, TSOP19238, TSOP14838, and TSOP12238 devices are designed to be functionally equivalent to the current standard 38- kHz devices in the TSOP4xxx, TSOP2xxx, TSOP58xxx, and TSOP59xxx series, while maximizing the operational range for all standard IR remote control applications. Typical industry standard protocols using pulse-distance coding are NEC code, Toshiba code, and Mitsubishi code, as well as derivations of these codes.

Each module includes a photo detector and preamplifier circuit, mounted within a 3-pin epoxy-encapsulated module with an integrated lens. Two standard package types are available as well as three industry-standard pin configurations.

The new devices are specified for operation at 5 V with a transmission range of 35 meters. The modules feature a carrier frequency of 38 kHz, and include an internal Automatic Gain Control (AGC) circuit for enhanced immunity against optical noise, as well as an internal metal shield for protection against EMI. The output of the new IR receivers is TTL- and CMOS-compatible. All four devices feature a maximum irradiance of 30 W/m2 with the specific pin-out options, forward current requirements and minimum irradiance characteristics summarized in the table below.

New IR Receiver Modules Optimized for Pulse Distance Coding: Summary Table

Module 1 Pin 1 Pin 2 Pin 3 Forward current for 35-meter distance(mA) Minimum Irradiance(mW/m2)
TSOP18238 OUT GND Vs 400 0.30
TSOP19238 OUT Vs GND 400 0.30
TSOP14838 OUT GND Vs 250 0.15
TSOP12238 OUT Vs GND 250 0.15

Samples and production quantities of the four new IR receiver modules are available now, with lead times of four weeks for large orders.
