FAQs

What is LA7674?

The LA7674 is a vertical deflection output integrated circuit (IC) designed for CRT (cathode ray tube) televisions. It is commonly used in TVs for generating the vertical deflection current needed to scan the electron beam vertically across the screen, allowing for the display of images and videos.

How Does LA7674 Work?

The LA7674 works by receiving vertical synchronization signals from the TV's circuitry and generating the necessary waveform to drive the vertical deflection coil. This waveform controls the positioning of the electron beam on the screen vertically, enabling the display of the entire image frame by frame.

How Many Pins does LA7674 have and What are the Functions of the Pinout Configuration?

The LA7674 is typically housed in a multi-pin inline package. The pinout configuration includes:

VCC: Power supply pin for the IC.
VCC1: Additional power supply pin for specific functions.
Y1, Y2: Vertical deflection output pins.
DY: Vertical sawtooth waveform input.
AMPL. CONT: Amplitude control input.
V-SYNC: Vertical synchronization input.
AC COUPL: AC-coupling capacitor pin.
GY: Guard pin for increased stability.

What are the Pros and Cons of LA7674?

Pros:

Specialized Function: Specifically designed for vertical deflection in CRT televisions.
Integrated Solution: Combines multiple functions in a single IC, simplifying the design of TV circuits.
Reliable Performance: Well-established IC known for its reliable operation in TV applications.

Cons:

Obsolete Technology: CRT technology is becoming less common, limiting the use of the LA7674.
Complexity: Requires understanding of TV circuitry to effectively integrate and troubleshoot.
Heat Dissipation: May generate heat during operation, requiring proper thermal management.

Are There Any Equivalents/Alternatives to LA7674 for Recommendation?

The LA7837 from Sanyo is a similar vertical deflection output IC for CRT TVs.
Alternatives to the LA7674 include the TDA8351 from Philips and the STRF6654 from Sanken Electric.
